The non-invasive glucometer and/or the invasive glucometer may aggregate an invasive glucose measurement and a non-invasive glucose measurement into the data batch. A data analytics application on the cloud-based server may be configured to: integrate the invasive glucose measurement and the non-invasive glucose measurement; identify a correlation between the invasive glucose measurement and the non-invasive glucose measurement; and/or generate a predictive model based on the invasive glucose measurement and the non-invasive glucose measurement.

BACKGROUND

The symptoms of a chronic health condition can be a significant factor in the quality of life for an individual experiencing the chronic health condition. Proper management of the chronic health condition can lead to outcomes which greatly improve the individual's quality of life compared to outcomes experiences when the chronic health condition is improperly and/or inadequately managed. For example, proper management of a chronic health condition may include taking regular measurements of various body functions, either directly or indirectly. Such measurements may provide critical information necessary for proper management of the chronic health condition. Obtaining measurements may be challenging and/or time-consuming, and the individual may accordingly be unlikely to obtain the measurements. Without the measurements, the chronic health condition may be improperly and/or inadequately managed, leading to poor outcomes for the individual where the individual experiences serious, even life-threatening symptoms of the chronic health condition.

Elements specific to a given example may be described regarding that particular example embodiment. A person having ordinary skill in the art will understand that a given element need not be the same and/or similar to the specific portrayal of a related element in any given figure or example embodiment in order to share features of the related element.

Same may refer to sharing all features and similar may refer to sharing a substantial number of features or sharing materially important features even if a substantial number of features are not shared. May should be interpreted in the permissive sense and should not be interpreted in the indefinite sense. Additionally, use of is regarding embodiments, elements, and/or features should be interpreted to be definite only regarding a specific embodiment and should not be interpreted as definite regarding the invention as a whole.

A conventional system for chronic health condition management, such as a glucose monitoring system for managing diabetes, may include a measurement component, an analysis component, and a user interface. The measurement component may measure an analyte of a user. The measurement component may take a measurement of the analyte invasively, minimally invasively, and/or non-invasively. The analysis component may determine an amount of the analyte based on the measurement, and the user interface may display the amount to the user. Some glucose monitoring systems, for example, may have a lancet for pricking the user to draw blood from the user, a test strip onto which the blood is placed, and an analysis and display unit that determines the amount of glucose in the blood and displays the amount to the user. Some glucose monitoring systems may include a probe that continually measures glucose in the user's interstitial fluids. Some glucose monitoring systems measure glucose non-invasively by processing light reflected from and/or passed through a body part of the user.

Invasive monitoring systems have become a bane to individuals with diabetes. Lancet pricks are painful and, depending on the frequency required and the specific user's sensitivity to the pricks, can cause ongoing discomfort and pain for the user. The use of a large number of lancets and/or test strips frequently, especially multiple times per day, may lead to the spread of disease by a careless user. Furthermore, individuals may dread the process enough to avoid it completely, which may lead to poor management of the health condition. The individual may experience severe symptoms due to poor management.

Minimally invasive systems may require penetrating the user's skin, such as by an incision through which a probe is inserted. Minimally invasive systems may not be as accurate as invasive monitoring systems, and thus may incorrectly diagnose a state of an analyte. This may be due to a “time dilation” where the interstitial fluid does not reflect the current blood glucose levels, but rather is delayed by up to 20 minutes. For example, a minimally invasive system may indicate the user is within a safe range when the user is actually hyperglycemic or hypoglycemic. This may cause the user to unknowingly experience adverse symptoms of hyperglycemia or hypoglycemia. Accordingly, minimally invasive systems may be inadequate in properly managing the user's chronic health condition.

Non-invasive monitoring systems may be susceptible to drift of the measurements due to the influence of other variables related to the analyte. For example, the user's hydration level may change, which may change a percentage of the user's blood that is glucose without changing an absolute amount of blood glucose. This may similarly result in the non-invasive monitoring system indicating the user is in a safe range when the user is actually hypoglycemic or hyperglycemic.

Systems, devices, and methods for chronic health condition management as described herein may include an invasive measurement device, a non-invasive measurement device, a server, a user interface, and a network over which the measurement devices, the server, and the interface communicate. The invasive measurement device may take a first analyte isolation measurement. The non-invasive measurement device may take a second analyte isolation measurement concurrently with the first analyte measurement. The non-invasive measurement device may take continuous or semi-continuous analyte measurements after the analyte isolation measurement. The continuous or semi-continuous analyte measurements may measure changes in the analyte from the first or second analyte isolation measurement. The first analyte isolation measurement, second analyte isolation measurement, and/or the continuous or semi-continuous analyte measurements may be communicated to the server and/or the user interface. Together, the invasive measurement device, the non-invasive measurement device, the server, and/or the user interface may form a continuous analyte monitoring system. The continuous analyte monitoring system may reduce the user's pain and/or discomfort from frequent invasive measurement, eliminate non-analyte variables, and provide continuous information that the user may utilize to control variation of the analyte.

FIG. 1B illustrates a side perspective exploded view of the first sensor 112, according to an embodiment. Some of the features in FIG. 1B are the same as or similar to some of the features in FIG. 1A as noted by same reference numbers, unless expressly described otherwise. Additionally, reference may be made to features shown in FIG. 1A and not shown in FIG. 1B. In one embodiment, the first sensor 112 may include a miniaturized spectrometer. The first sensor 112 may include a filter 112 a, a collimator 112 b, and an optical sensor 112 c. In one embodiment, the filter 112 a may include an optical filter, such as a variable filter, a linear variable filter, an absorptive filter, a dichroic filter, a monochromatic filter, an infrared filter, an ultraviolet filter, a neutral density filter, a long-pass filter, a band-pass filter, a short-pass filter, a guided-mode resonance filter, a metal mesh filter, a polarizer filter, an arc welding filter, a wedge filter, and so forth. In another embodiment, the filter may include a Fabry-Perot Etalon filter.

The filter 112 a may include a linear variable filter. The linear variable filter may allow for selecting which wavelengths strike the optical sensor 112 c at a specific position on the optical sensor 112 c. This may allow a processor such as the processing unit 110 and/or the processing device 102 to, in turn, distinguish the relative intensities of wavelengths reflected from a tissue to determine which wavelengths are most strongly reflected from the tissue relative to an initial intensity of those wavelengths as emitted from a light source. The processor may determine, based on the reflected wavelengths, one or more parameters, constituents, and/or conditions of the tissue. For example, light having a first wavelength may strike a first region of the optical sensor 112 c corresponding to a first region of the filter 112 a. The first wavelength may correspond to a constituent of a user's blood. The optical sensor 112 c may communicate the intensity of the first wavelength to the processor. The processor may process the first wavelength based on an emitted intensity of the wavelength, an expected attenuation of the wavelength, and/or other attenuation factors to determine an amount of the constituent in the user's blood. Different constituents of the user's blood may transmit and/or reflect wavelengths of light at different intensities. The filter 112 a may pass different wavelengths to different positions on the optical sensor 112 c. The optical sensor 112 c may pass the intensities of the corresponding wavelengths to the processor, and the processor may determine an amount of a blood constituent based on the relative intensities of the wavelengths.

In an embodiment, the filter 112 a may include an absorptive filter. The absorptive filter may be formed to have distinct cutoff edges between regions of the absorptive filter corresponding to different wavelength ranges. Furthermore, the absorptive filter may be manufactured of a durable and/or flexible material. In an embodiment, the filter 112 a may include a dichroic filter, which may also be referred to as an interference filter. The dichroic filter may be variable. The dichroic filter may allow for very precise selection of wavelengths to be passed through the filter 112 a. For example, the dichroic filter may have a transmission profile with a narrow peak, such as a full-width half max (FWHM) wavelength range of 50 nm, 40 nm, 30 nm, 25 nm, 20 nm, 10 nm, 5 nm, and/or 1 nm. The dichroic filter may be implemented in embodiments where the filter 112 a is incorporated into a sensor for measuring sensitive phenomena. The sensitive phenomena may include various physiological parameters, conditions, and/or constituents for which small-percentage changes, such as less than or equal to a 50 percent change, results in dramatically different outcomes. For example, the sensitive phenomenon may include a blood acidity level. A healthy blood acidity may include a pH of 7.4. A blood pH less than or equal to 6.8 or greater than or equal to 7.8 may result in irreversible cell damage. In another example, the sensitive phenomenon may include bone density.

In an embodiment, the filter 112 a may include a grism. In an embodiment, the filter 112 a may include a prism coupled to a diffraction grating. The grism or the coupled prism and diffraction grating may be referred to as the grism. In various embodiments, the prism may include a dispersion prism and/or a prismatic sheet, such as a Fresnel prism. In various embodiments, the diffraction grating may include a ruled grating, a holographic grating, a transmission grating, a reflective grating, a blazed holographic grating, a concave grating, an aberration-corrected concave grating, a constant deviation monochromator concave grating, a Rowland type concave grating, a blazed holographic concave grating, a sinusoidal holographic grating, a sinusoidal ruled grating, a pulse compression grating, and so forth. In an embodiment, the diffraction grating may include a volume phase holographic (VPH) grating. In an embodiment, the diffraction grating may diffract impinging light along one dimension or along two dimensions.

In one embodiment, the collimator 112 b may include a device that restricts beam(s) of particles or waves passing into the first sensor 112, such as light in visible and/or non-visible wavelengths, to specific directions of motion, angles, or ranges of angles to become more aligned in a specific direction as the beam(s) travels through the first sensor 112. The collimator 112 b may restrict a spatial cross-section of the beam(s). In an embodiment, the collimator 112 b may restrict the beam(s) along one dimension and/or along two dimensions.

The collimator 112 b may be formed in one or more of a variety of ways. In various embodiments, the collimator 112 b may be formed of one or more microtubes. In an embodiment, the collimator 112 b may include a plurality of microtubes, where a microtube of the plurality of microtubes is defined by one or more walls encircling a through-channel. A microtube of the plurality of microtubes may have a width ranging from 10 microns to 150 microns, and/or a height ranging from 30 microns to 500 microns. For example, the microtube may have a height equal to less than a thickness of 4 pages of printer paper, and a width equal to less than a thickness of 1 page of printer paper. The microtubes may be prepared separately and joined together, such as by a binder, or the microtubes may be prepared together. For example, the walls of the microtubes may be formed of CNTs. A catalyst layer may be patterned on a substrate forming an impression of the plurality of microtubes, and the CNTs may be grown on the catalyst layer, forming the walls encircling the through-channels to form the microtubes. In another embodiment, the collimator 112 b may include a volume of material through which pores and/or apertures are formed. The volume of material may, for example, include a photoresist material. The pores and/or apertures may be etched through the photoresist material, such as by photolithography or plasma etching.

The collimator 112 b may be positioned against the filter 112 a and/or the optical sensor. For example, the collimator 112 b may be disposed between the filter 112 a and the optical sensor 112 c, or the filter 112 a may be disposed between the collimator 112 b and the optical sensor 112 c as illustrated in FIG. 5C. In an embodiment, a wall forming a microtube of the collimator 112 b may be aligned normal to a surface of the filter 112 a and/or a surface of the optical sensor 112 c. In an embodiment, light may pass through the filter 112 a and the collimator 112 b may allow light within a range of normal incidence passing from the filter 112 a to impinge on the optical sensor 112 c. In another embodiment, the collimator 112 b may allow light to impinge on the filter 112 a within a range of normal incidence. In yet another embodiment, the collimator wall may be aligned at a non-normal angle relative to the surface of the filter 112 a and/or the surface of the optical sensor 112 c. The angle may correspond to an angle of separated light leaving the filter 112 a.

The optical sensor 112 c may be operable to convert light rays into electronic signals. For example, the optical sensor 112 c may measure a physical quantity of light such as intensity and translate the measurement into a form that is readable by the processor such as an amount of current corresponding directly to the intensity of the light. In an embodiment, the optical sensor 112 c may include a semiconductor. The semiconductor may have one or more bandgaps corresponding to a wavelength and/or wavelength range. The semiconductor may be arranged into an array, such as an array of pixels, corresponding to regions of the filter 112 a such as the first region 528 a, the second region 528 b, and so forth. In another example, the optical sensor 112 c may include a temperature sensor, a velocity liquid level sensor, a pressure sensor, a displacement (position) sensor, a vibration sensor, a chemical sensor, a force radiation sensor, a pH-value sensor, a strain sensor, an acoustic field sensor, an electric field sensor, a photoconductive sensor, a photodiode sensor, a through-beam sensor, a retro-reflective sensor, a diffuse reflection sensor, and so forth.

The optical sensor 112 c may include a segment such as a pixel. In an embodiment, the optical sensor 112 c may include a plurality of the segment arrange in an array, such as an array of pixels. The sensor segment may be aligned with a region of the filter 112 a. The segment may have an identifier such that the processor may associate the segment with the region of the filter. The identifier may enable the processor to determine a wavelength of light detected by the segment of the optical sensor 112 c. For example, in one embodiment, the optical sensor may include a first sensor segment aligned with a first filter region, a second sensor segment aligned with a second filter region, and so forth. The first sensor segment may be identified by the processor as detecting a wavelength and/or range of wavelengths that may correspond to a passband of the first filter region. For example, wavelengths ranging from 400 nm to 449 nm may pass unfiltered through the first filter region. The unfiltered light may strike the first sensor segment, and the first sensor segment may, in response generate an electrical signal that may be transmitted to the processor. The processor may identify the electrical signal as being transmitted by the first sensor segment and may identify that signals transmitted by the first sensor segment may be generated by light having a wavelength ranging from 400 nm to 449 nm.

In one embodiment, the filter 112 a, the collimator 112 b, and the optical sensor 112 c may be stacked together to form the first sensor 112. In one example, the filter 112 a, the collimator 112 b, and the optical sensor 112 c may be integrated together to form an integrated sensor body.

For example, the biometric sensor 208 may include a miniaturized impedance sensor and/or a miniaturized spectrometer.

The wearable device 100 may be positioned on the wrist 204 a so that the biometric sensor 208 may be positioned over the first muscular-walled tube 206 a. In an embodiment, the first muscular-walled tube 206 a may be positioned in the wrist 204 a approximate to an underside of the wrist 204 a. For example, the first muscular-walled tube 206 a may be positioned in the wrist 204 a between a dermal layer of the wrist 204 a and one or more bones in the wrist 204 a. The biometric sensor 208 may be positioned against the underside of the wrist 204 a. This may optimize an accuracy and/or precision of a measurement taken by the biometric sensor 208 from the first muscular-walled tube 206 a. The wearable device 100 may use the measurements to determine a physiological condition of the user. Positioning the biometric sensor 208 against the underside of the wrist may also reduce a chance of the biometric sensor 208 being struck or otherwise damaged in a way that may affect the accuracy and/or precision of the measurement taken by the biometric sensor 208. For example, an outside of the wrist 204 a may be exposed to other surfaces against which the wearable may be struck, whereas an underside of the wrist 204 a may be less likely to strike other surfaces because it faces towards a body of the user.

FIG. 2B illustrates the wearable device 100 on an arm 204 b of the user, according to an embodiment. Some of the features in FIG. 2B are the same as or similar to some of the features in FIGS. 1A-2A as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-2A and not shown in FIG. 2B. The arm 204 b may include a second muscular-walled tube 206 b. The second muscular-walled tube 206 b may be, in an embodiment, a vein or an artery. The wearable device 100 may be positioned on the arm 204 b so that the biometric sensor 208 may be positioned over the second muscular-walled tube 206 b.

In various embodiments, the wearable device 100 may be worn by the user on another body part such as a hand of the user, a forearm of the user, an elbow of the user, a chest of the user, a neck of the user, a head of the user, a torso of the user, a waist of the user, a thigh of the user, a calf of the user, a knee of the user, an ankle of the user, or a foot of the user. Accordingly, the body part may include a muscular-walled tube.

In various embodiments, the biometric sensor 208 may be pressed against a skin surface of the body part. The biometric sensor 208 and/or wearable device 100 may be positioned on the body part over a region of the body part where the muscular-walled tube may be closest to the skin surface for the body part. The biometric sensor 208 may be positioned against the body part where the muscular-walled tube may be positioned between the biometric sensor 208 and a skeletal structure of the body part. This may minimize a distance between the biometric sensor 208 and the muscular-walled tube, which in turn may optimize one or more biometric measurements taken by the biometric sensor 208 from the muscular-walled tube. In various embodiments, the biometric sensor 208 and/or the wearable device 100 may be positioned on the body part over a region of the body part where the skeletal structure is positioned between the skin surface and the muscular-walled tube. This may maximize the distance between the biometric sensor 208 and the muscular-walled tube, which in turn may minimize effects of the muscular-walled tube on measurements taken by the biometric sensor 208. For example, the user may desire to take a measurement of a relatively static physiological condition, physiological parameter, and/or physiological constituent such as a bone density of the user and/or a body fat percentage of the user. The muscular-walled tube may be dynamic and may interfere with measuring the static physiological condition, physiological parameter, and/or physiological constituent. Accordingly, maximizing the distance between the biometric sensor 208 and the muscular-walled tube may result in more accurate and/or precise measurements of the static physiological condition, physiological parameter, and/or physiological constituent. In various embodiments, the biometric sensor 208 and/or the wearable device 100 may be positioned on the body part such that the biometric sensor 208 may be approximate the muscular-walled tube and the skeletal structure such that the muscular-walled tube is not between the skeletal structure and the biometric sensor 208 and the skeletal structure is not between the muscular-walled tube and the biometric sensor 208.

The elements of the health device network configuration 300 a, including the devices, the server, and/or the network communication links, may form an independent and/or isolated network. The independent and/or isolated network may include a LAN, CAN, MAN, IAN, and/or WAN. The health device network configuration 300 a may be physically isolated from devices outside the health device network configuration 300 a. For example, wireless and/or hardline connections may be limited to in-network devices.

The data analytics application 306 e may correlate the time-indexed invasive blood glucose measurement with at least one of the series of continuous, time-indexed blood glucose measurements from the wearable device 100. The correlation may include a time correlation, where the two measurements have the same time index. The cloud-based server 306 may communicate the correlation to the wearable device over the second network communication link 310 b. The cloud-based server 306 may communicate the correlation to the invasive analyte measurement device 302 over the fourth network communication link 310 d.

The wearable device 100, the invasive analyte measurement device 302, the peripheral measurement device(s) 304, the cloud-based server 306, and/or the user device 308 may be physically located near each other. For example, the user device 308, the wearable device 100, the invasive analyte measurement device 302, the peripheral measurement device(s) 304, and/or the cloud-based server 306 may be located in the same room, in the same building, and/or on the same campus. In an embodiment, the user device 308, the wearable device 100, the invasive analyte measurement device 302, the peripheral measurement device(s) 304, and/or the cloud-based server 306 may be located on the same health care campus. In another embodiment, the user device 308, the wearable device 100, the invasive analyte measurement device 302, the peripheral measurement device(s) 304, and/or the cloud-based server 306 may be located in the same hospital.

The user device 308, the cloud-based server 306 the wearable device 100, the invasive analyte measurement device 302, and/or the peripheral measurement device(s) 304 may be physically located remotely from each other. For example, the user device 308, the cloud-based server 306, the wearable device 100, the invasive analyte measurement device 302, and/or the peripheral measurement device(s) 304 may be located in a different building, on a different campus, in a different metropolitan area, in a different country, and/or on a different continent from each other.

For example, the cloud-based server 306 may be physically located in a data center and the user device 308 may be located in a call center. In another embodiment, the peripheral measurement device(s) 304 may be located in a medical office and the wearable device 100 may be worn by the user and/or may accompany the user as the user travels from one location to another. The user may carry the invasive analyte measurement device 302 with the user, may leave the invasive analyte measurement device 302 at the user's home, and so forth. The cloud-based server 306 may be located in a data center and the user device 308 may be located in a call center.

The health device network configuration 300 a may allow a user to aggregate data from a plurality of different measurement devices to perform data analysis. The aggregated data may provide health insights that separate measurements alone may not provide. For example, correlations between changes in blood glucose levels and changes in blood oxygen saturation may provide insights into treatment strategies for individuals with diabetes. Passing data from multiple devices through one device to the cloud-based server 306 may provide data integrity to ensure measurements are captured. For example, if each individual device communicates separately and directly with the cloud-based server 306, connectivity interruptions may not be caught and may result in missing data. However, if data is routed through one device, connectivity can be more easily monitored and repaired if there are issues, ensuring that more data is captured. Additionally, it may be more efficient to send data from multiple devices in a single data packet to prevent data loss due to data traffic congestion at the cloud-based server 306.

In an embodiment, wherein the wearable device 100 (i.e. a non-invasive glucometer) and/or the invasive analyte measurement device 302 may aggregate an invasive glucose measurement and a non-invasive glucose measurement into a data batch. The data analytics application 306 e may: integrate the invasive glucose measurement and the non-invasive glucose measurement; identify correlation between the invasive glucose measurement and the non-invasive glucose measurement; or generate a predictive model based on the invasive glucose measurement and the non-invasive glucose measurement. The predictive model may predict corrections to the non-invasive glucose measurement based on the invasive glucose measurement. The user device may display to the user the invasive glucose measurement, the non-invasive glucose measurement, the data batch, and/or the processed data.

In an embodiment, the invasive analyte measurement device 302 or the wearable device may aggregate a physiological characteristic measurement by one or more of the peripheral measurement devices 304 with the invasive glucose measurement and the non-invasive glucose measurement in the data batch.

FIG. 3B illustrates a method 312 of processing and/or correlating raw measurement data at a cloud-based server 306, the raw measurement data collected by measurement devices networked to the cloud-based server in a health device network such as the configuration described regarding FIG. 3A, according to an embodiment. Some of the features in FIG. 3B are the same as or similar to some of the features in FIGS. 1A-3A as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-3A and not shown in FIG. 3B. The cloud-based server may include the cloud-based server 306. The measurement devices may include the wearable device 100, the invasive analyte measurement device 302, and/or the peripheral measurement device(s) 304.

The method 312 may include receiving, at the cloud-based server 306, first data from a first measurement device and/or second data from a second measurement device (block 312 a). The first data and/or the second data may include raw, unprocessed measurement data. For example, the first data and/or the second data may include electrical current and/or electrical potential data. The first data and/or the second data may include minimally processed measurement data. For example, the first measurement device may locally process raw data to yield a measurement value or values such as blood glucose level, weight, blood pressure, and so forth. The measurement value or values may form the first data. Similarly, the second measurement device may locally process raw data to yield a measurement value or values and/or compile the measurement value or values to form the second data.

The method 312 may include processing, at the cloud-based server, the first data to determine a first measurement value or set of values associated with the first data, and/or processing, at the cloud-based server, the second data to determine a second measurement value or set of values associated with the second data (block 312 b). The cloud-based server may store the first data and/or the second data after processing or may discard the first data and/or the second data after processing. The cloud-based server may store the first measurement value or set of values. The cloud-based server may tag the first measurement value or set of values as being associated with the first measurement device. The cloud-based server may store the second measurement value or set of values. The cloud-based server may tag the second measurement value or set of values as being associated with the second measurement device.

The method 312 may include correlating, at the cloud-based server, the first measurement value or set of values with the second measurement value or set of values (block 312 c). The first data and/or the second data may be time-indexed. The time indexing may enable correlation of the first data to the second data such that the cloud-based server may determine that a measurement by the first measurement device was taken at or proximate to a same time as a measurement by the second measurement device. Proximate may refer to a temporal proximity relative to measurement type. For example, the first measurement value may be weight and the second measurement value may be blood pressure. The time indexing may be daily. In another example, the first measurement device may include the invasive analyte measurement device 302 and the second measurement device may include the wearable device 100. The first measurement value may be blood glucose invasively measured and the second measurement value may be blood glucose non-invasively measured. The time indexing may be by minute, such that the first measurement was taken within one minute of the second measurement. Additionally, the time indexing may enable the cloud-based server to compare non-concurrent measurement data, such as correlating measurements taken by the first measurement device at a first time to measurements taken by the second measurement device at a second time subsequent to the first time.

The correlating of the first measurement value or set of values with the second measurement value or set of values may include multivariate analysis to determine a strength of a relationship between a first underlying physiological characteristic associated with the first measurement value or set of values and a second underlying physiological characteristic associated with the second measurement value or set of values. The cloud-based server may store the relationship strength and/or update the relationship strength as the cloud-based server receives more measurement data from the first measurement device and/or the second measurement device. The relationship strength may be correlative such that changes in the first underlying physiological characteristic are accompanied by changes in the second underlying physiological characteristic. The relationship strength may be causative such that changes in the first underlying physiological characteristic cause changes in the second underlying physiological characteristic. The relationship strength may show the first underlying physiological characteristic and the second underlying physiological characteristic are loosely related and/or unrelated.

The method 312 may include storing, on the cloud-based server, the first data, the second data, first measurement value or set of values, the second measurement value or set of values, and/or the correlation between the first measurement value or set of values and the second measurement value or set of values (block 312 d). The method 312 may include receiving, at the cloud-based server, a request from a user device for the first data, the second data, first measurement value or set of values, the second measurement value or set of values, and/or the correlation between the first measurement value or set of values and the second measurement value or set of values (block 312 e). The method 312 may include transmitting, from the cloud-based server, the first data, the second data, first measurement value or set of values, the second measurement value or set of values, and/or the correlation between the first measurement value or set of values and the second measurement value or set of values (block 312 f).

The user device may include the wearable device 100, the invasive analyte measurement device 302, one or more of the peripheral measurement device(s) 304, and/or the user device 308. The request may be received by the cloud-based server before the first data and/or the second data is received by the cloud-based server. The request may include a standing request such that the cloud-based server automatically processes and transmits, upon receipt of the first data and/or the second data, the first data, the second data, the first measurement value or set of values, the second measurement value or set of values, and/or the correlation between the first measurement value or set of values and the second measurement value or set of values. The cloud-based server may transmit the first data, the second data, the first measurement value or set of values, the second measurement value or set of values, and/or the correlation between the first measurement value or set of values and the second measurement value or set of values without and/or before receiving the request. For example, the cloud-based server may include instructions to automatically transmit the first data, the second data, the first measurement value or set of values, the second measurement value or set of values, and/or the correlation between the first measurement value or set of values and the second measurement value or set of values.

The request may be received simultaneously with receiving the first data and/or the second data. For example, the first data and/or the second data may include the request. The request may be received before the cloud-based server processes the first data and/or the second data. For example, the cloud-based server may store the first data and/or the second data and may be prompted to process the first data and/or the second data upon receiving a request for the first data, the second data, the first measurement value or set of values, the second measurement value or set of values, and/or the correlation between the first measurement value or set of values and the second measurement value or set of values. The request may be received after the cloud-based server processes the first data and/or the second data.

The request may include a generic request for data. For example, the request may not specify a type of data requested, where type may refer to whether the data is raw data, processed data, correlated data, measurement values, and so forth. The request may include an identifier that may identify a type of device and/or a specific device requesting the data. The cloud-based server may include instructions on what data to transmit based on the type of device and/or the specific device requesting the data. For example, the identifier may indicate the requesting device is the wearable device 100. The cloud-based server may store instructions to transmit a packet of data including a correlation between a hydration measurement by the wearable device and a blood glucose measurement taken by the invasive analyte measurement device 302.

In another embodiment, a method of processing and/or correlating raw measurement data at a cloud-based server 306 may include: aggregating a set of raw data into a raw data batch; transmitting the raw data batch to the cloud-based server 306; receiving a confirmation the raw data batch is received by the cloud-based server 306; deleting the raw data batch from local memory after receiving the confirmation; and receiving processed data from the cloud-based server, the processed data based on the data batch and output by the data analytics application 306 e. The raw data batch may include: a first measurement by the invasive analyte measurement device 302 and a second measurement by a non-invasive glucometer; and/or the first measurement, the second measurement, and a third measurement by a health measurement device such as one of the peripheral measurement devices 304. A data point of the set of raw data may include: an electronic signal correlated to a device tag indicating a measurement device outputting the electronic signal; an analyte level; or a value providing indication of a quality or a quantity of a physiological characteristic. The data analytics application 306 e may be hidden on the cloud-based server 306 from the invasive analyte measurement device 302, the non-invasive glucometer, and the health measurement device.

In an embodiment, a method of processing and/or correlating raw measurement data at a cloud-based server 306 may include: taking the first measurement; and receiving, directly from the non-invasive glucometer, the second measurement. The invasive analyte measurement device 302 may aggregate the set of raw data. In an embodiment, a method may include: taking the second measurement; and receiving, directly from the invasive glucometer, the first measurement. The non-invasive glucometer may aggregate the set of raw data. Transmitting the raw data batch may be prompted by: the raw data batch occupying a threshold amount of physical memory; the raw data batch comprising a threshold number of the first measurement or the second measurement; a threshold amount of time passing after the first measurement is taken; a third measurement being taken by the invasive glucometer; and/or receiving a request for the raw data batch.

Additionally, reference may be made to features shown in any of FIGS. 1A-3B and not shown in FIG. 3C. The health device network configuration 300 b may include the wearable device 100, the invasive analyte measurement device 302, the one or more peripheral measurement device(s) 304, the cloud-based server 306, and the user device 308.

The wearable device 100 and the cloud-based server 306 may communicate over the second network communication link 310 b. The invasive analyte measurement device 302 and the peripheral measurement device(s) 304 may communicate over the third network communication link 310 c. The invasive analyte measurement device 302 and the cloud-based server 306 may communicate over the fourth network communication link 310 d. The cloud-based server 306 and the user device 308 may communicate over the fifth network communication link 310 e. The peripheral measurement device(s) 304 and the user device 308 may communicate over the sixth network communication link 310 f.

The peripheral measurement device(s) 304 and the user device 308 may be networked in a PAN, a NAN, a LAN, a CAN, a WAN, an IAN, or via the Internet. In various embodiments, the sixth network communication link 310 f may include a direct communication link. For example, the sixth network communication link 310 f may include a Bluetooth™ connection. In another example, the seventh network communication link 310 g may include a hardwire ethernet connection between an ethernet port on an individual peripheral measurement device and an ethernet port on the user device 308. In various embodiments, the sixth network communication link 310 f may include an indirect communication link. For example, the sixth network communication link 310 f may include a WiFi connection routed between the peripheral measurement device(s) 304 and the user device 308 via a network switch and/or WiFi router. In another example, the sixth network communication link 310 f may include two or more physically different types of links, such as a wired link and a wireless link, routed over a local network or over the Internet. The peripheral measurement device(s) 304 may have Internet Protocol (IP) addresses which may be accessible by a device connected to the Internet.

In various embodiments, the health device network configuration 300 b may be situated in a healthcare provider office or on a healthcare provider campus. The peripheral measurement device(s) 304 may include devices for obtaining physiological characteristics of a patient such as the patient's height, weight, blood pressure, resting pulse, blood oxygen saturation, blood sugar level, and so forth. The peripheral measurement device(s) 304 may be networked to the user device 308 via the sixth network communication link 310 f, and the user device 308 may be networked to the cloud-based server 306 via the fifth network communication link 310 e.

In some embodiments, data and/or measurements collected by the peripheral measurement device(s) 304 may be processed and/or analyzed at the peripheral measurement device taking the measurement and/or collecting the data. For example, a weight scale may determine a weight based on an output by a strain gauge sensor and display the weight on a display integrated into the weight scale.

In some embodiments, data and/or measurements collected by the peripheral measurement device(s) 304 may be communicated to the user device 308 via the sixth network communication link 310 f and processed and/or analyzed at the user device 308. For example, a blood pressure monitor may transmit raw data to a handheld computing device such as a tablet. The tablet may process the raw data and determine a blood pressure corresponding to the raw data transmitted by the blood pressure monitor. The tablet may display the blood pressure to a user of the tablet such as a healthcare provider.

In some embodiments, data and/or measurements collected by the peripheral measurement device(s) 304 may be communicated to the user device 308 via the sixth network communication link 310 f and communicated by the user device 308 to the cloud-based server 306 via the fifth network communication link 310 e. The cloud-based server 306 may process and/or analyze the raw data. For example, a healthcare provider may evaluate a patient's health status over a period of time, such as over an hour, over several hours, over a day, over several days, and so forth. The evaluation may involve collecting time-indexed raw data by several peripheral measurement device(s) 304. The time-indexed raw data may be communicated to the cloud-based server 306 through the user device 308. Individual peripheral measurement devices may process the respective raw data collected by the individual peripheral measurement device and display values determined based on the raw data to the patient and/or a user viewing the individual peripheral measurement device. The user device 308 may process the raw data communicated from the peripheral measurement device(s) 304 and display the raw data from the peripheral measurement device(s) 304 to a user such as a healthcare provider. The cloud-based server 306 may aggregate the time-indexed raw data in the raw data database 306 c, and the data analytics application 306 e may process the time-indexed raw data to generate diagnostics of the patient's health status. For example, the data analytics application 306 e may determine based on an EKG reading, sonographic heartbeat measurement data, and pulse oximetry measurement data that the patient has a leaky heart valve.

Direct communication of data between the user device 308 and the peripheral measurement device(s) 304 may allow a user greater control over and/or on-demand access to measurement data. For example, the user may require a weight measurement. The patient may stand on the scale and the patient's weight may automatically populate on the user device 308 as the weight measurement is received at the user device 308 directly from the weight scale. The weight may simultaneously be aggregated at, for example, the wearable device 100 with other measurement data and transmitted to and stored at the cloud-based server 306 for analysis. Thus, direct communication by the weight scale with the user device 308 makes the measurement immediately available to the user while aggregation of the weight measurement with other measurement data enables more detailed analysis of the patient's overall health.

The elements of the health device network configuration 300 c, including the wearable device 100, the invasive analyte measurement device 302, the peripheral measurement device(s) 304, the cloud-based server 306, and/or the user device 308 may be fully interconnected with each other such that the elements may be communicatively coupled to each other element. Accordingly, the health device network configuration 300 c may be fully meshed, which may include another network communication link between the wearable device 100 and the invasive analyte measurement device 302. Elements of the health device network configuration 300 c may be configured, i.e. via programming and/or instructions stored and executed on processors local to the elements, to process, store, and/or display data collected and/or measurements taken by the peripheral measurement device(s) 304, the wearable device 100, and/or the invasive analyte measurement device 302. The peripheral measurement device(s) 304, the wearable device 100, and/or the invasive analyte measurement device 302 may be configured to transmit the data and/or measurements to the cloud-based server 306. The cloud-based server 306 may be configured to analyze the data and/or measurements and transmit the analysis to the peripheral measurement device(s) 304, the wearable device 100, the invasive analyte measurement device 302, and/or the user device 308. Examples and/or embodiments described regarding the health device network configuration described herein may be implemented in health device network configurations where network communication links are provided to enable such examples and/or embodiments.

The health device network configuration 300 c may represent a fully-meshed or semi-meshed network. In a fully-meshed embodiment, the health device network configuration 300 c may include a network connection between the wearable device 100 and the invasive analyte measurement device 302. The fully-meshed network configuration may allow for network redundancy to ensure measurement data is not lost. For example, the cloud-based server 306 may prioritize storage of aggregated measurement data from the wearable device 100 and/or the invasive analyte measurement device 302. The peripheral measurement device(s) 304 may transmit measurement data to the wearable device 100 and/or the invasive analyte measurement device 302 for aggregation of the measurement data. Simultaneously, the peripheral measurement device(s) 304 may transmit the measurement data to the cloud-based server 306. The cloud-based server may silo the measurement data received directly from the peripheral measurement device(s) 304 for comparison with aggregated measurement data received from the wearable device 100 and/or the invasive analyte measurement device 302. If the aggregated measurement data includes all the siloed measurement data, then the siloed measurement data may be discarded. However, if the aggregated measurement data is missing data that is included in the siloed data, the aggregated measurement data may be supplemented with the missing data from the siloed data. Thus, the redundancy of the fully- or semi-meshed network configuration may ensure data is not lost.

FIG. 3E illustrates a method 314 of efficiently displaying data on a user device, the data collected by measurement devices and analyzed by a cloud-based server, according to an embodiment. Some of the features in FIG. 3E are the same as or similar to some of the features in FIGS. 1A-3D as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-3D and not shown in FIG. 3E. The user device may include the user device 308. The measurement devices may include the wearable device 100, the invasive analyte measurement device 302, and/or the peripheral measurement device(s) 304. The cloud-based server may include the cloud-based server 306. The user device, the measurement devices, and the cloud-based server may communicate via a health device network such as the configurations described regarding FIGS. 3A, 3C and/or 3D.

The method 314 may include receiving a request at the user device for data (block 314 a). The request may be received by a direct user of the user device. The request may include instructions to display the data to the user by the user device. The method 314 may include determining whether the data requested is for measurement data or for analyzed data (block 314 b). Measurement data may include raw measurement data such as electric current or potential data. Measurement data may include processed measurement data in the form of a measurement value such as blood glucose level, weight, blood pressure, and so forth. Analyzed data may include measurement trends, correlations between measurements taken by different devices, whether a measurement value indicates a healthy condition or an unhealthy condition, and so forth. The method 314 may include receiving measurement data directly from the measurement data (block 314 c). The method 314 may include receiving analyzed data directly from the cloud-based server (block 314 d). The method 314 may include displaying the requested data to the user (block 314 e).

The method 314 may efficiently allocate device memory and/or processing capacity for devices in the health device network. Measurement devices may be subject to hardware constraints such as size and power constraints. Such constraints may make it inefficient to analyze data locally at the measurement device, especially when analysis may include analysis of data from other devices. Data analysis may place large demands on transitory memory and may consume significant amounts of power. Data analysis may process large amounts of data, and the measurement device may not have enough local memory to store the large amount of data. Accordingly, it may be most efficient for the measurement devices to communicate measurement data to the cloud-based server, for the cloud-based server to store and analyze the data, and for the user device to request the analyzed data from the cloud-based server. Additionally, it is more likely that requested analyzed data may include large amounts of data taken over relatively long time frames and not susceptible to strong variation over short time frames, such as a time frame over which a user may view the requested data, which may range from a few seconds to a few hours. A user may request measurement data to directly view live measurement data. Sending single measurements and/or live measurement data may have relatively low memory and/or power requirements and may therefore be more efficiently communicated directly to the user device as opposed to routing the data through the cloud-based server.

FIG. 3F illustrates a method 316 of routing measurement data through a measurement device hub in a health device network such as the configurations described regarding FIGS. 3A, 3C and/or 3D, according to an embodiment. Some of the features in FIG. 3F are the same as or similar to some of the features in FIGS. 1A-3E as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-3E and not shown in FIG. 3F. The measurement device hub may include an analyte measurement device such as the invasive analyte measurement device 302 and/or a non-invasive analyte measurement device such as the wearable device 100. In an embodiment, the invasive analyte measurement device 302 may include an invasive glucometer and the non-invasive analyte measurement device may include a non-invasive glucometer. The wearable device 100 may be referred to as a non-invasive glucometer. The measurement data may be collected by the measurement device hub and/or a peripheral device such as the peripheral measurement device(s) 304. The data may be routed to a server such as the cloud-based server 306 and/or a user device such as the user device 308.

The method 316 may include receiving measurement data at the measurement device hub (block 316 a). The measurement data may be collected by the measurement device hub or the peripheral device. The measurement data may include raw data and/or minimally processed data. The measurement data may include time indexing of the raw and/or minimally processed data. The measurement data may be indexed to a calendar and/or clock time, as opposed to an internal clock and/or time of the measurement device hub and/or the peripheral device. The method 316 may include accumulating the measurement in local memory of the measurement device hub (block 316 b). The method may include packaging the measurement data in local memory as a data batch (block 316 c). The data batch may include a time index for the measurement data in the data batch. For example, the data batch may include measurement data from a blood pressure cuff, a weight scale, and an invasive glucometer. The data batch may include a first data column for blood pressure data, a second data column for weight, a third data column for blood glucose, and a fourth data column for time. The data batch may include a row for a time corresponding to a measurement. Columnar entries in a row may include measurements taken at the time corresponding to the row.

The method 316 may include transmitting the data batch from the measurement device hub to the server and/or the user device (block 316 d). The measurement device hub may be prompted to transmit the data batch periodically, such as upon expiration of an amount of time since a previous data batch transmission. The measurement device hub may be prompted to transmit the data batch by a request. The request may be made by a user of the measurement device hub. For example, the measurement device hub may include an invasive glucometer with a user interface. The user may request, via the user interface the data batch be transmitted to the server and/or the user device. The request may be made from the server and/or the user device. The request may be automatic based on a maximum and/or minimum data batch size. For example, the measurement device hub may include instructions to transmit the data batch after the data batch reaches a threshold size. Upon receiving the request, the measurement device hub may “close” the data batch by redirecting measurement data received after the request to a different data batch.

The method 316 may include listening for and/or receiving at the measurement device hub a confirmation the data batch is received by a target (block 316 e). For example, the target may include the server and/or the user device. The server and/or the user device may transmit a receipt confirmation to the measurement device hub after the data batch is received by the server and/or the user device. The method 316 may include deleting the data batch from the measurement device hub local memory (block 316 f). The measurement device hub may include instructions to delete the data batch after the confirmation is received from the target.

The method 316 may ensure measurement data security, minimize the necessity of storage at the measurement device, and/or prevent reverse-engineering of proprietary data analytics programs. Health data privacy may be a great concern for patients. Local memory in measurement devices may be susceptible to attacks to obtain a patient's private health data. Thus, aggregating measurement data, transmitting the measurement data to a secure device, and deleting the data from local memory may protect against attempts to steal data from a local measurement device. Additionally, deleting historical measurement data may minimize memory requirements, thus allowing electronic components of measurement devices to be smaller, more compact, and/or more efficient. Sequestering analytics programming and/or instructions to a secure cloud-based server (e.g. the cloud-based server 306) may enhance the security of the programming and/or instructions and allow for the use of proprietary and/or trade secret analytics programming and/or instructions while minimizing the risk the programming and/or instructions are uncovered and stolen by a competitor.

FIG. 4A illustrates the user device 308 described regarding FIGS. 3A-C as a mobile phone 402 running the mobile application 308 a, according to an embodiment. Some of the features in FIG. 4A are the same as or similar to some of the features in FIGS. 1A-3F as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-3F and not shown in FIG. 4A. The mobile phone 402 may include a touchscreen 402 a displaying a GUI 402 b. Via the GUI 402 b, the mobile application 308 a may display information to the user and may accept input from the user. The information may be displayed to the user via one or more modules. The modules may, in an embodiment, include a rewards module 404 a, a history module 404 b, a messages module 404 c, a devices module 404 d, a condition management module 404 e, and/or a menu module 404 f. Various other embodiments may include these and/or other modules, including an appointment module, a share module, a healthcare provider finder module, a social networking module, a disease selection module, and so forth. For example, in an embodiment, the social networking module may allow the patient to share health information such as progress towards goals in disease management. In an embodiment, the disease module may allow the patient to select a disease to manage with the mobile application 308 a, and the GUI 402 b may adjust according to the selected disease, such as in what data is displayed, what goals are displayed, a color theme associated with the disease, and so forth.

In one embodiment, the mobile application 308 a may be tailored for the patient, the third party, a non-medical user, and so forth. The tailoring may be the same for different users, or the tailoring may be different for different users. For example, a first instance of the mobile application 308 a may be tailored for use by the patient and a second instance of the mobile application 308 a may be tailored for use by a healthcare provider such as a nurse, doctor, practice manager, and so forth. In another example, a first instance of the mobile application 308 a may be tailored for use by the patient and a second instance of the mobile application 308 a may be tailored for use by a third party. The third-party may, for example, be a friend of the patient, a family member of the patient, or a care provider of the patient. The first instance of the mobile application 308 a may display detailed personal information about the patient such as the patient's demographic information, the patient's vitals, the patient's goals and/or progress towards those goals, the patient's medications, the patient's medical history, information about the patient's medical provider, information about the patient's medical insurer, and so forth. The second instance of the mobile application 308 a may display limited information about the patient. For example, the second instance of the mobile application 308 a may display some of the patient's live vitals such as the patient's heart rate, the patient's electrocardiograph, the patient's glucose levels, the patient's hydration level, and so forth. The second instance of the mobile application 308 a may display the patient's goals and/or progress towards those goals. In one embodiment, the patient may select via the first instance of the mobile application 308 a what information is visible via the second instance of the mobile application 308 a, up to and including all information available to the patient via the first instance of the mobile application 308 a.

The modules may include programming and/or instructions for receiving inputs from the user via the GUI 402 b and/or programming and/or instructions for generating outputs. The outputs may be displayed to the user via the GUI 402 b, stored in memory of the user device 308, and/or sent from the user device 308 to another device such as the cloud-based server 306. The outputs may correspond to the inputs received from the user and/or the outputs may correspond to data received by the user device 308 from another device such as the cloud-based server 306. For example, the user may input information into one of the modules via the GUI 402 b. The module may cause the information to be stored in the memory of the user device 308. The module may additionally and/or alternatively cause the information to be communicated to another device such as the cloud-based server 306. The module may additionally and/or alternatively cause the information to be displayed to the user. In another example, the user device 308 may receive information from another device such as the cloud-based server. The programming and/or instructions of the module may cause the information to be stored in the memory of the user device. The programming and/or instructions of the module may cause the information to be displayed via the GUI 402 b to the user. The information may prompt an input from the user.

The GUI 402 b may show a display generated by, for example, a processing device of the user device 308. The display may be tailored to show particular information for a particular user and/or type of user. In various embodiments, the cloud-based server 306 may include a wide array of information that may be useful to a variety of different users. However, not all the information may be useful and/or of interest to all the different users. Thus, the display may be tailored for the particular user to include information relevant to the particular user and/or to exclude information irrelevant to the particular user. For example, the cloud-based server 306 may store information about insurance costs associated with an individual and a medical chart associated with the individual. A display tailored for an insurance provider user may include the insurance costs and may exclude the medical chart. A display tailored for a healthcare provider may include the medical chart and may exclude the insurance costs.

The rewards module 404 a may record the user's goals and/or track the user's progress towards the goals. The goals may be health-related goals. For example, the goals may include an exercise goal, a sleep goal, a blood glucose goal, a stress level goal, and so forth. The exercise goal may include exercising for a certain amount of time, exercising a certain number of times, having a heart rate over a certain level, and so forth. The sleep goal may include sleeping for a certain amount of time, achieving a certain amount of rapid eye movement (REM) sleep, and so forth. The blood glucose goal may include regular glucose measurement with a glucometer, wearing the wearable device 100 for a number of days in a row, and so forth. The blood glucose goal may include decreasing the user's fasting hemoglobin A_(1c) (A_(1c)) level, decreasing a range of variation of the user's blood glucose level, and so forth. The stress level goal may include decreasing the user's average resting heart rate, decreasing the user's average resting blood pressure, and so forth. In an embodiment, the goal may be associated with an insurance provider. For example, the goal may relate to decreasing a cost of disease management by the insurance provider, such as by decreasing the patient's A_(1c) level. A decreased A_(1c) level may lead to decreased costs for the insurance provider, such as by decreasing doctor or hospital visits and/or decreasing payment for measurement supplies, medicine, and/or insulin supplies. The rewards module 404 a may include programming and/or instructions for awarding one or more rewards as the user records progress towards the user's goals. The rewards may include points. The points may be added as the user progresses towards the goals and/or may be removed as the user digresses from the goals. In an embodiment, the user may redeem the points, such as for a gift card, a rebate, a prize, and so forth.

The history module 404 b may include programming and/or instructions to store and/or display past and/or present data regarding one or more physiological characteristics of the user. The past and/or present data may include a graph, a table, a list, a current value, a past value, a maximum value, a minimum value, an average value, an optimal value, an amount of time within a particular and/or specified range, a coefficient of variation, information about trends in the data, a rate of change of the data, and so forth. For example, the past and/or present data may include a graph of physiological characteristic measurements indexed to a time stamp and/or indexed over a time interval. The physiological characteristics may include a heart rate, a blood pressure level, a hydration condition, a blood glucose level, and so forth. The blood glucose level may include a distinction between an invasively measured blood glucose level and a non-invasively measured blood glucose level. In one embodiment, the history module 404 b may be programmed to display a graph showing continuous blood glucose measurements taken non-invasively from the user. The blood glucose measurements may be taken by the wearable device and communicated to the user device 308 via the cloud-based server 306.

In another example, the message may be from a family member, friend, and/or acquaintance with whom the patient shares health information. The family member, friend, and/or acquaintance may have access to a separate instance or the same instance of the user device 308 application than the patient. The message may be from a health care provider using the medical practitioner application 308 d, and so forth. The message may be from an insurance provider using the insurance provider portal 308 e. The message may include an automated message sent by an entity such as a healthcare provider company, a health insurance company, and so forth. The message notification may include a new message notification, an unread message notification, and so forth. The messages module 404 c may include programming and/or instructions to receive input from the user and/or generate a message based on the user input. The message may be sent via the mobile application 308 a to another instance of the user device 308 application. The message may include an email message, a text message, an internet message, and so forth. The message drafting interface may accept the user input to generate the message based on the user input.

The devices module 404 d may include programming and/or instructions which may correlate measurement data received by the user device 308 with a corresponding measurement device. The programming and/or instructions may include assigning an identifying tag to the corresponding measurement device, searching received measurement data for the identifying tag, and/or categorizing the received measurement data with the corresponding measurement device.

The condition management module 404 e may include a list of health conditions that may be managed by the user via the mobile application 308 a. The health conditions may be conditions of the user or of others associated with the user. For example, the user may manage the user's hydration via the mobile application 308 a and may monitor the glucose levels of another person, such as the user's child, via the mobile application 308 a. Selecting a condition in the condition management module 404 e may enable a display to be generated on the GUI 402 b which may include information tailored to the condition selected and the person for whom the condition is being managed. For example, the user may wish to see the last time the user's child performed a finger-stick glucose measurement. The user may select a diabetes condition icon in the condition management module 404 e. The mobile application 308 a may load a display and information corresponding to the child's glucose measurements. In an embodiment, a user may monitor the same condition for two or more people. For example, the user may monitor the user's hydration level and a hydration level of the user's child. Selecting a hydration icon in the condition management module 404 e may cause a pop-up window to be generated which may prompt the user to select the person for whom the user wishes to see hydration information.

The graph 500 may include a time axis 502, an analyte level axis 504, and a curve 506 generated by analyte level measurements taken at particular points in time. An initial analyte level 504 a may be measured at a beginning time 502 a. The curve 506 may include local valleys 506 a and local peaks 506 b. In various embodiments, the graph 500 may be displayed to a user such as the patient, a healthcare provider, an insurance provider, another third party, and so forth. The graph 500 may accordingly include boundary indicators based on an initial measurement line 510 a. The boundary indicators may delineate a range of analyte levels from the initial analyte level 504 a that may be acceptable and/or healthy for the patient. The boundary indicators may include an upper warning line 510 b, a lower warning line 510 c, an upper danger line 510 d, and a lower danger line 510 e.

The time axis 502 may be referenced to an absolute time, such as a clock and/or calendar time. The time axis 502 may be referenced to a relative time. For example, the beginning time 502 a may include a clock time, such as 8:00 am, or a relative time of zero minutes. Subsequent times along the time axis 502 may be referenced from the beginning time 502 a. The time axis 502 may include intervals in seconds, minutes, hours, days, and so forth. Similarly, the analyte level axis 504 may reference an absolute analyte level with a minimum of zero analyte. The analyte level axis 504 may reference a relative analyte level. The relative analyte level may be set at zero for a starting analyte measurement level and may include positive and negative values corresponding to changes in the analyte level from the starting analyte measurement level. The starting analyte measurement level may include a safe analyte level and/or an initial analyte level. In one embodiment, the initial analyte level 504 a may be set as a “zero” mark, the upper warning line 510 b and the upper danger line 510 d may represent positive changes from the initial analyte level 504 a represented by positive values, and the lower warning line 510 c and the lower danger line 510 e may represent negative changes from the initial analyte level 504 a represented by negative values.

The beginning time 502 a may start when a first measurement is taken. The first measurement may determine an absolute value for the initial analyte level 504 a. The initial measurement line 510 a may be set to the initial analyte level 504 a. The first measurement may be taken by the wearable device 100. The first measurement may be taken by an invasive measurement device such as the invasive analyte measurement device 302. In an embodiment, the first measurement may include a glucose measurement taken by an invasive glucometer using blood drawn by, for example, a finger prick. Subsequent measurements that may fill out the curve 506 for a remainder of the time period 510 after the beginning time 502 a may be taken by a miniaturized spectrometer and/or a bioimpedance sensor embedded in the wearable device 100. The miniaturized spectrometer may be aligned with a blood vessel such as a vein or artery. A light source embedded in the wearable device 100 may shine light through the blood vessel. The miniaturized spectrometer may determine an amount of glucose in the blood vessel based on relative intensities of constituent wavelengths of the light that pass through and/or reflect off of blood within the blood vessel.

In various embodiments, the curve 506 may include a sequence of discreet measurements conjoined by a line to form a continuous representation of the discreet measurements. The discreet measurements may be demarked by one or more indicators, such as symbols, which may indicate a precise time and level for the measurement. The indicators may be conjoined by the line. In various embodiments, the curve 506 may include the indicators and may omit the line conjoining the indicators. The curve 506 may be smoothed by a smoothing algorithm. In various embodiments, the curve 506 may include continuous measurements represented by a continuous line. The curve 506 may be displayed to a user, such as the patient via the wearable device 100, a healthcare provider via the user device 308, and so forth. The curve 506 may be displayed as the curve 506 is being generated. For example, the time period 512 may include a fixed time period, such as a current day, and hour, a week, a month, and so on. The graph 500 may display the time period 512 and may show analyte measurements as the analyte measurements are taken, indexed to the time during the day the measurements are taken. A user may view the graph at 8:00 am and see measurements taken between 12:00 am and 8:00 am. The user may review the graph at 10:00 am and see measurements taken between 12:00 am and 10:00 am, and so on. Accordingly, the curve 506 may be updated in real-time.

In various embodiments, the upper danger line 510 d may indicate a dangerously high amount of analyte in the patient at and/or over which the patient is more likely than not to experience adverse and/or severe symptoms due to the patient's analyte level being too high. In various embodiments, the upper danger line 510 d may indicate a dangerous difference in analyte level above the initial analyte level 504 a. The dangerously high amount of analyte may include an absolute level of the analyte based on data gathered from a population of individuals. The dangerously high amount of analyte may include an absolute level of the analyte based on data gathered from the patient on the amount of analyte at and/or above which the patient experiences adverse and/or severe symptoms. The adverse and/or severe symptoms may correspond to a condition related to the analyte. For example, in embodiments where the analyte is glucose, glucose levels at and/or above the upper danger line 510 d may indicate the patient is hyperglycemic. The adverse and/or severe symptoms may include dizziness, nausea, light-headedness, profuse sweating, irregular heartbeat, loss of consciousness, and so forth. The patient may experience symptoms of hyperglycemia at and/or above the upper danger line 510 d.

In various embodiments, the lower danger line 510 e may indicate a dangerously low amount of analyte in the patient at and/or below which the patient is more likely than not to experience adverse and/or severe symptoms due to the patient's analyte level being too low. In various embodiments, the lower danger line 510 e may indicate a dangerous difference in analyte level below the initial analyte level 504 a. The dangerously low amount of analyte may include an absolute level of the analyte based on data gathered from a population of individuals. The dangerously low amount of analyte may include an absolute level of the analyte based on data gathered from the patient on the amount of analyte below the initial analyte level 504 a at which the patient experiences adverse and/or severe symptoms. The adverse and/or severe symptoms may correspond to a condition related to the analyte. For example, in embodiments where the analyte is glucose, glucose levels at and/or below the lower danger line 510 e may indicate the patient is hypoglycemic. The patient may experience symptoms of hypoglycemia at and/or below the lower danger line 510 e.

In various embodiments, the upper danger line 510 d and the lower danger line 510 e may correspond to statistically abnormal amounts of the analyte. In various embodiments, the upper danger line 510 d and the lower danger line 510 e may correspond to statistically abnormal variations in the amount of analyte from the initial analyte level 504 a. The statistically abnormal amounts of the analyte and/or the statistically abnormal variations in the amount of analyte from the initial analyte level 504 a may be based on data taken from a population of individuals and/or from data taken from the patient. The statistically abnormal amounts of the analyte and/or the statistically abnormal variations in the amount of analyte from the initial analyte level 504 a may correspond to a number of standard deviations from the initial analyte level 504 a. For example, the statistically abnormal amounts of the analyte and/or the statistically abnormal variations in the amount of analyte from the initial analyte level 504 a may define a range of amounts of analyte above and below the initial analyte level 504 a at or within two standard deviations from the initial analyte level 504 a.

The upper warning line 510 b may indicate an amount of analyte in the patient within a threshold of the dangerously high amount of analyte. The threshold may be within a certain percentage of the dangerously high amount of analyte indicated by the upper danger line 510 d. The threshold may be within an absolute amount of the dangerously high amount of analyte. The threshold may be within a percentage of the dangerously high amount of analyte. The percentage may be based on a difference between the initial analyte level 504 a and the dangerously high amount of analyte. The upper warning line 510 b may indicate an amount of analyte in the patient at and/or above which the patient is more likely than not to experience minor adverse symptoms. The minor adverse symptoms may correspond to a condition related to the analyte. For example, the analyte may include blood glucose. The minor adverse symptoms may include increased resting heart rate, increased resting blood pressure, sweating, excessive thirst, and so forth. The upper warning line 510 b may indicate the patient is close enough to experiencing hyperglycemia to take mitigating steps to avoid hyperglycemia. The mitigating steps may include taking a shot of insulin.

The lower warning line 510 c may indicate an amount of analyte in the patient within a threshold of the dangerously low amount of analyte. The threshold may be within a certain percentage of the dangerously low amount of analyte indicated by the lower danger line 510 e. The threshold may be within an absolute amount of the dangerously low amount of analyte. The threshold may be within a percentage of the dangerously low amount of analyte. The percentage may be based on a difference between the initial analyte level 504 a and the dangerously low amount of analyte. The lower warning line 510 c may indicate an amount of analyte in the patient at and/or above which the patient is more likely than not to experience minor adverse symptoms. The minor adverse symptoms may correspond to a condition related to the analyte. For example, the analyte may include blood glucose. The lower warning line 510 c may indicate the patient is close enough to experiencing hypoglycemia to take mitigating steps to avoid hypoglycemia. The mitigating steps may include drinking a sugary beverage.

In various embodiments, the upper warning line 510 b and the lower warning line 510 c may correspond to statistically significant amounts of the analyte. In various embodiments, the upper danger line 510 d and the lower danger line 510 e may correspond to statistically significant variations in the amount of analyte from the initial analyte level 504 a. The statistically significant amounts of the analyte and/or the statistically significant variations in the amount of analyte from the initial analyte level 504 a may be based on data taken from a population of individuals and/or from data taken from the patient. The statistically significant amounts of the analyte and/or the statistically significant variations in the amount of analyte from the initial analyte level 504 a may correspond to a number of standard deviations from the initial analyte level 504 a. For example, the statistically significant amounts of the analyte and/or the statistically significant variations in the amount of analyte from the initial analyte level 504 a may define a range of amounts of analyte above and below the initial analyte level 504 a at or within one standard deviation from the initial analyte level 504 a.

The curve 506 may represent continuous measurements of the patient's analyte levels during the time period 512. The continuous measurements may be monitored and/or compared to the dangerously high amount of analyte and the dangerously low amount of analyte. For example, the processor of the wearable device 100 may be programmed to generate a warning as the patient's analyte level reaches and/or exceeds the upper warning line 510 b, and/or as the patient's analyte level reaches and/or dips below the lower warning line 510 c. The warning may include an audible and/or visual signal communicated via a user interface of the wearable device 100. The warning may include a signal communicated to another device such as the cloud-based server 306 and/or the user device 308.

The cloud-based server 306 may store the warning and/or use the warning in an analytics process. An individual patient's tolerance ranges for a given analyte, such as glucose, may differ from statistically average tolerance ranges for a population. A tolerance range may include a range of analyte levels outside of which the patient is more likely than not to experience adverse symptoms. The data analytics application 306 e may determine the individual patient's tolerance ranges by correlating the patient's analyte levels with other concurrent physiological characteristics of the patient. For example, the data analytics application 306 e may correlate the patient's analyte levels with concurrent heart rate data and concurrent sweat rate data. The data analytics application 306 e may determine a statistical correlation between the analyte levels and the onset of adverse symptoms. The data analytics application 306 e may determine a statistical correlation between the analyte levels and relief from the adverse symptoms. In a specific embodiment, the data analytics application 306 e may compare blood glucose data to heart rate data, blood pressure data, and/or sweat rate data. The data analytics application 306 e may correlate a sudden drop in blood pressure and a sudden increase in sweating with a blood glucose level. The data analytics application 306 e may set the measured blood glucose level corresponding to the sudden drop in blood pressure and sudden increase in sweating as a danger level and may set a warning level between a safe level and the danger level. The warning level may include a percentage of a difference between the safe level and the danger level, such as 75 percent, 80 percent, 85 percent, 90 percent, and so forth. The safe level may be based on a fasting blood glucose level and/or on a postprandial blood glucose level for the patient and/or for a population of which the patient is a member.

The cloud-based server 306 may store information regarding tolerable rates of change of the patient's analyte levels. For example, a too-rapid drop in blood glucose level may indicate an imminent onset of severe hypoglycemic symptoms, including shock, severe nausea, loss of consciousness, and so forth. The cloud-based server 306 may include alerts associated with maximum and/or minimum rates of change of the patient's analyte levels and generate alerts when the patient's current rate of change in the analyte exceeds the maximum or minimum threshold. For example, the patient may experience a rapid increase in blood alcohol content, and the patient's blood alcohol content may sustain at a high level and/or continue increasing over time. The cloud-based server may generate an alert that the patient is consuming too much alcohol. The alert may be transmitted to another user associated with the patient and/or to the patient, such as via the wearable device 100, to alert the patient and/or the other user that the patient's alcohol consumption is too high. This may help prevent alcohol poisoning and/or another alcohol-related injury.

A shape of the curve 506 may vary depending on the type of analyte measured to generate the analyte levels. The shape of the curve 506 may indicate a behavior of the patient corresponding to the analyte. In various embodiments, the analyte may be blood glucose. The shape of the curve 506 may include sharp increases corresponding with mealtimes, followed by less sharp decreases corresponding to metabolizing of the blood glucose. The shape of the curve 506 may include local valleys 506 a corresponding to periods of fasting and sharp local peaks 506 b corresponding to mealtimes. In various embodiments, the analyte may be blood cells, electrolytes, serum albumin, immunoglobulins, proteins, blood-clotting factors, and so forth. The shape of curves corresponding to these analytes, respectively, may vary according to how the analytes individually vary with time.

In an embodiment, the information displayed in the graph 500, such as the initial measurement line 510 a, the upper warning line 510 b, the lower warning line 510 c, the upper danger line 510 d, and/or the lower danger line 510 e may be stored in a device and compared to real-time analyte measurements taken from the patient. The device may include the wearable device 100, the invasive analyte measurement device 302, the cloud-based server 306, and/or the user device 308. As a real-time analyte measurement exceeds a warning level and/or a danger level, an alert may be communicated via the device. The alert may be communicated via the wearable device 100 and/or the invasive analyte measurement device 302. The cloud-based server 306 may generate the alert and communicate the alert to the wearable device 100, the invasive analyte measurement device 302, and/or the user device 308. The alert may be generated by the user device 308 and/or communicated to the user and/or the patient via the user device 308. The user device 308 may communicate the alert to the cloud-based server 306, the wearable device 100, and/or the invasive analyte measurement device 302.

In one example, the wearable device 100 may determine a real-time measurement exceeds a danger level. The wearable device 100 may communicate an alert to the patient and send the alert to the user device 308 via the cloud-based server 306. For example, the alert communicated to the patient may instruct the patient to take an analyte measurement such as an invasive glucose measurement (i.e. a finger prick measurement). A healthcare provider may view the alert on the user device 308, such as through one of the applications 308 a-d. The alert may prompt the user to attempt to contact the patient to determine the patient's health status. For example, the alert may prompt the user to call the patient or contact the patient via a message on the wearable device 100. Based on an urgency of the alert, such as a warning alert or a danger alert, the user may be prompted to contact emergency personnel if the user is unable to contact the patient.

FIG. 5B illustrates a method 514 of taking time-indexed analyte measurements and communicating warnings to a user when the measurements exceed set levels, according to an embodiment. Some of the features in FIG. 5B are the same as or similar to some of the features in FIGS. 1A-5A as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-5A and not shown in FIG. 5B. In various embodiments, the method 514 may be performed on one device such as the wearable device 100, the invasive analyte measurement device 302, the cloud-based server 306, the user device 308, and so forth. In various embodiments, elements of the method 514 may be performed on separate devices, where the devices form a health device network.

The method 514 may include receiving an initial analyte level from an invasive analyte measurement device such as the invasive analyte measurement device 302 (block 514 a). In an embodiment, the analyte may be glucose and the invasive analyte measurement device may include an invasive glucometer. The method 514 may include setting an initial analyte measurement of a non-invasive analyte measurement device equal to the initial analyte level (block 514 b). In an embodiment, the non-invasive analyte measurement device may include the wearable device 100. The method 514 may include setting a warning level and a danger level based on the initial analyte level and/or based on a coefficient of variation of the patient's analyte levels. (block 514 c). The warning level may include the upper warning line 510 b and/or the lower warning line 510 c. The danger level may include the upper danger line 510 d and/or the lower danger line 510 e. The warning level and/or the danger level may be based on a statistical amount of expected change from a base analyte level, i.e. the coefficient of variation. The base analyte level may include, for example, a fasting glucose level. The coefficient of variation may be based on statistical data calculated from measurements taken over time from the patient. Accordingly, the coefficient of variation may be specific to the patient. In an embodiment, the danger level and/or the warning level may be determined based on a combination of the coefficient of variation and the initial analyte level.

The method 514 may include receiving time-indexed analyte measurements from the non-invasive analyte measurement device subsequent to the initial analyte measurement by the non-invasive analyte measurement device (block 514 d). The time indexing may be relative to an initial time at which the initial analyte level was taken, where the initial time is a zero time. The time indexing may be relative to an absolute time such as a calendar time and/or a clock time. The method 514 may include comparing the subsequent measurement to the initial analyte level, the warning level, and/or the danger level (block 514 e). The method 514 may include communicating a first warning to a user when a subsequent measurement exceeds the warning level (block 514 f). For example, the first warning may be communicated when the subsequent measurement is higher than the upper warning line 510 b or lower than the lower warning line 510 c. The method 514 may include communicating a second warning to the user when the subsequent measurement exceeds the danger level (block 514 g). For example, the second warning may be communicated when the subsequent measurement is higher than the upper danger line 510 d or lower than the lower danger line 510 e.

In an embodiment, the device may include the wearable device 100 and the user may include a patient wearing the wearable device 100 from whom the measurements may be taken. The wearable device 100 may generate the first warning and/or the second warning via the display device 104. The first warning and/or the second warning may include visual communication such as words, flashing lights, and colors. The first warning and/or the second warning may include audible communication such as a sound and/or tone. The first warning and/or the second warning may include tactile communication such as vibration. In an embodiment, the device may include the cloud-based server 306. The user may include the patient and/or a healthcare provider. The cloud-based server 306 may send the first warning and/or the second warning as an alert to the patient's mobile phone. The cloud-based server 306 may send the first warning and/or the second warning as an alert via the mobile application 308 a, the user portal 308 b, the point of care engagement center application 308 c, and/or the medical practitioner application 308 d.

FIG. 6 illustrates a graph 600 of analyte measurements taken over consecutive time periods 602 a-e and drifting from an initial reference measurement 602, according to an embodiment. Some of the features in FIG. 6 are the same as or similar to some of the features in FIGS. 1A-5B as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-5B and not shown in FIG. 6 . The graph 600 includes the curve 506 referenced to the time axis 502 and the analyte level axis 504. The curve 506 includes measurements take over a first time period 602 a, a second time period 602 b, a third time period 602 c, a fourth time period 602 d, and a fifth time period 602 e. Over the consecutive time periods 602 a-e, the curve 506 includes a drift 604 from the initial reference measurement 602. The drift 604 may be indicated by a difference between the initial measurement line 510 a and the curve 506 during the first time period 602 a as compared with a difference between the initial measurement line 510 a and the curve 506 during the fifth time period.

In various embodiments, the drift 604 may reflect a change in a range of measurements for the analyte in the patient. For example, the analyte may include glucose. The drift may indicate glucose is not being removed from the patient's blood efficiently and/or effectively and the patient's average blood glucose levels are rising. In various embodiments, the drift 604 may reflect a change in a physiological element related to the analyte being measured that affects the measurement of the analyte. For example, the analyte may include glucose and the physiological element may include water. The analyte may be measured by in vivo optical spectroscopy, such as by using the wearable device 100 with the first sensor 112 being a miniaturized spectrometer. Optical spectroscopy may yield a concentration of the glucose in the patient's blood as opposed to an absolute amount of glucose in the patient's blood. As a hydration condition of the patient changes, a concentration of glucose in the user's blood may change even as an absolute level of glucose in the user's blood may remain consistent within a pattern of variation for the level of glucose. The drift 604 may therefore indicate a change in the patient's hydration condition. In embodiments where optical spectroscopy is performed for analyte measurement, the drift 604 may indicate a change in an amount of interference in the patient's blood by another analyte than the analyte of interest. The other analyte may absorb the same wavelengths of light as absorbed by the analyte of interest. For example, as the patient's blood contains more water, which may absorb the same wavelengths of light as glucose in the blood.

In various embodiments, the drift 604 may be caused by a physiological element having a significantly longer change period than a change period for the analyte. For example, the analyte may be glucose and the physiological element may be water. Glucose in the patient's blood may change dramatically over a period of a few minutes as the patient eats. Water in the patient's blood may change dramatically over a period of hours as the patient becomes dehydrated, such as during an extended period of physical exertion where the patient sweats. The decrease in water in the patient's blood may result in an overall increase in a concentration of glucose in the patient's blood. A device that measures concentration may output a measurement that gives an appearance blood glucose is increasing even though it may actually be decreasing, maintaining at a level, or increasing slower than it appears to be increasing.

FIG. 7A illustrates a graph 700 of analyte measurements taken over the consecutive time periods 602 a-e with indicators for the initial analyte level 504 a and subsequent validated and/or reinitialized analyte levels 702 a-d, according to an embodiment. Some of the features in FIG. 7A are the same as or similar to some of the features in FIGS. 1A-6 as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-6 and not shown in FIG. 7A. A first analyte measurement curve 704 a extends over the first time period 602 a. A first measurement of the first analyte measurement curve 704 a may be set equal to the initial analyte level 504 a, and subsequent analyte measurements that fill out the first analyte measurement curve 704 a may be referenced to the initial analyte level 504 a as changes from the initial analyte level 504 a. The initial measurement line 510 a may provide a visual indication across the first time period 602 a of the initial analyte level 504 a and differences between subsequent measurements, as indicated by the first analyte measurement curve 704 a, and the initial analyte level 504 a.

In various embodiments, the initial analyte level 504 a may be validated and/or reinitialized to identify and/or compensate for drift in the analyte measurements attributable to another physiological element that may skew the analyte measurements. The initial analyte level 504 a may be validated at an end of the first time period 602 a. For example, the first time period 602 a may be 24 hours. At the end of 24 hours, the initial analyte level 504 a may be validated. In an embodiment, the initial analyte level 504 a may be set by a measurement taken by an invasive analyte measurement device, such as the invasive analyte measurement device 302. The subsequent analyte measurements that fill out the first analyte measurement curve 704 a may be taken by a non-invasive analyte measurement device such as the wearable device 100. The initial analyte level 504 a may be validated by a second measurement taken by the invasive analyte measurement device. The measurement taken by the invasive analyte measurement device may be less susceptible to skewing by the other physiological element than measurements taken by the non-invasive analyte measurement device. Accordingly, the second measurement by the invasive analyte measurement device may not reflect drift, such as the drift 604, that accrues over the first time period 602 a in the first analyte measurement curve 704 a.

The second measurement by the invasive analyte measurement device may yield a first validated and/or reinitialized analyte measurement level 702 a. The first validated and/or reinitialized analyte measurement level 702 a may be discontinuous with the first analyte measurement curve 704 a. A time along the time axis 502 at which the second measurement by the invasive analyte measurement device is taken may demark an end of the first time period 602 a and a beginning of a second time period 602 b. The first validated and/or reinitialized analyte measurement level 702 a may demark a starting analyte level against which non-invasive analyte measurements taken during the second time period 602 b may be referenced. The non-invasive analyte measurements taken during the second time period 602 b may be represented on the graph 700 by a second analyte measurement curve 704 b. A first measurement of the second analyte measurement curve 704 b may be set equal to the first validated and/or reinitialized analyte measurement level 702 a. A first validated and/or reinitialized measurement line 706 a may provide a visual indication across the second time period 602 b of the first validated and/or reinitialized analyte measurement level 702 a.

In various embodiments, the non-invasive analyte measurements may be validated and/or reinitialized periodically by invasive analyte measurements to identify and/or compensate for the drift. Accordingly, a third measurement by the invasive analyte measurement device may yield a second validated and/or reinitialized analyte measurement level 702 b. A time along the time axis 502 at which the third measurement by the invasive analyte measurement device is taken may demark an end of the second time period 602 b and a beginning of a third time period 602 c. The second validated and/or reinitialized analyte measurement level 702 b may demark a starting analyte level against which non-invasive analyte measurements taken during the third time period 602 c may be referenced. The non-invasive analyte measurements taken during the third time period 602 c may be represented on the graph 700 by a third analyte measurement curve 704 c. A first measurement of the third analyte measurement curve 704 c may be set equal to the second validated and/or reinitialized analyte measurement level 702 b. A second validated and/or reinitialized measurement line 706 b may provide a visual indication across the third time period 602 c of the second validated and/or reinitialized analyte measurement level 702 b.

Periodic validation and/or reinitialization may occur continuously. Accordingly, a fourth measurement by the invasive analyte measurement device may yield a third validated and/or reinitialized analyte measurement level 702 c; a fifth measurement by the invasive analyte measurement device may yield a fourth validated and/or reinitialized analyte measurement level 702 d; and so forth. The third validated and/or reinitialized analyte measurement level 702 c may demark a starting analyte level against which non-invasive analyte measurements taken during a fourth time period 602 d may be referenced; the fourth validated and/or reinitialized analyte measurement level 702 d may demark a starting analyte level against which non-invasive analyte measurements taken during a fifth time period 602 e may be referenced; and so forth. The non-invasive analyte measurements taken during the fourth time period 602 d may be represented on the graph 700 by a fourth analyte measurement curve 704 d; the non-invasive analyte measurements taken during the fourth time period 602 d may be represented on the graph 700 by a fourth analyte measurement curve 704 d; and so forth. A first measurement of the fourth analyte measurement curve 704 d may be set equal to the third validated and/or reinitialized analyte measurement level 702 c; a first measurement of the fifth analyte measurement curve 704 e may be set equal to the fourth validated and/or reinitialized analyte measurement level 702 d; and so forth. A third validated and/or reinitialized measurement line 706 c may provide a visual indication across the fourth time period 602 d of the third validated and/or reinitialized analyte measurement level 702 c; a fourth validated and/or reinitialized measurement line 706 d may provide a visual indication across the fifth time period 602 e of the fourth validated and/or reinitialized analyte measurement level 702 d; and so forth.

The validation and/or reinitialization of the analyte measurements (validation) may be distinguished from a calibration and/or baselining process. Calibration may generally refer to a process by which device settings are tuned to a particular standard. Baselining may generally refer to a process by which measurements are compared to a standard, or baseline, for differences between the measurements and the standard. The validation may include a process by which effects of a physiological element on a set of measurements directed toward an analyte are subtracted to yield a precise indication of the analyte. The validation may include calibration of the non-invasive analyte measurement device using the invasive analyte measurement device. For example, the processor of the non-invasive analyte measurement device may set an initial measurement by the non-invasive analyte measurement device to be equal to a measurement by the invasive analyte measurement device. The validation may include baselining by setting a standard measurement taken by the invasive analyte measurement device against which non-invasive analyte measurement device measurements are compared. The validation may additionally include extraneous validation of non-invasive analyte measurements using periodic invasive analyte measurements. The validation may additionally include resetting the one or more values stored in the non-invasive analyte measurement device to compensate for physiological changes in the patient. The validation may additionally include determining whether an invasive analyte measurement taken to validate the non-invasive analyte measurements is discontinuous with the non-invasive analyte measurements. The validation may additionally include keeping the invasive analyte measurement and validating the non-invasive analyte measurements if there is a discontinuity. The validation may additionally include discarding the invasive analyte measurement and continuing the non-invasive analyte measurements if the invasive analyte measurement is continuous with the non-invasive analyte measurements.

In various embodiments, a processor associated with the invasive analyte measurement device and/or the non-invasive analyte measurement device, such as the processor of the invasive analyte measurement device 302, the processing unit of the wearable device 100, the processor of the cloud-based server, and/or the processor of the user device 308, may determine a pattern in discontinuities between the analyte measurement curves 704 a-e. The pattern may be periodic in time. The pattern may be predictable. For example, the processor may determine a likelihood of a size and/or time of a next discontinuity and may update the likelihood based on an actual size and/or time of the next discontinuity. For example, the patient may exercise daily, causing the patient to sweat and skewing non-invasive measurements of the patient's blood glucose. The skewing may be temporary within one time period or may extend across two or more consecutive time periods, causing discontinuity between the analyte measurement curves corresponding to the two or more consecutive time periods. The processor may recognize a pattern in the skewing and may include one or more algorithms to predict and/or compensate for the skewing. For example, the processor may recognize the discontinuity has an average size in a same direction between the time periods. The processor may correlate a slope of the analyte measurement curves within the time periods to the average size of the discontinuity. The processor may subtract the slope and corresponding discontinuity from the analyte measurement curves to generate a corrected analyte measurement curve.

In an embodiment, the wearable device 100 may include one or more sensors and/or programming that may determine when the patient is engaged or about to become engaged in an activity that may lead to drift in the analyte measurement. For example, the wearable device 100 may interface with a calendar of the patient. The patient's calendar may indicate the patient plans to engage in strenuous physical activity, such as playing a sport and/or otherwise exercising. In another example, the wearable device 100 may include a GPS tracker. The GPS tracker may interface with a map which may indicate the patient's location at a given time. The patient may be located at a gym, and the wearable device 100 may infer that the patient is about to exercise. The wearable device 100 may anticipate a change in the patient's hydration condition corresponding with the calendar event and/or the patient's location and may thereby anticipate a drift in the patient's analyte measurements. The wearable device 100 may locally compensate for the anticipated and/or actually-measured drift or the wearable device 100 may communicate the anticipated drift to the cloud-based server 306 and the cloud-based server 306 may adjust the analyte measurements based on the measured and/or anticipated drift.

FIG. 7B illustrates a method 708 of validating non-invasive analyte measurements with an invasive analyte measurement after expiration of a time period, according to an embodiment. Some of the features in FIG. 7B are the same as or similar to some of the features in FIGS. 1A-7A as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-7A and not shown in FIG. 7B. In various embodiments, the method 708 may be performed on one device such as the wearable device 100, the invasive analyte measurement device 302, the cloud-based server 306, the user device 308, and so forth. In various embodiments, elements of the method 708 may be performed on separate devices, where the devices from a health device network.

The method 708 may include receiving an initial analyte level from an invasive analyte measurement device (block 708 a). The method 708 may include setting an initial analyte measurement of a non-invasive analyte measurement device equal to the initial analyte level (block 708 b). The method 708 may include receiving time-indexed analyte measurements from the invasive analyte measurement device subsequent to the initial measurement (block 708 c). The method may include receiving a validation level from the invasive analyte measurement device (block 708 d). The validation level may be based on an invasive analyte measurement. The validation level may be acquired at an end of a time period such as the first time period 602 a. The validation level may be acquired approximately concurrently with a final non-invasive analyte measurement taken at the end of the time period. The validation level may be acquired approximately concurrently with a most-recent non-invasive analyte measurement taken during the time period. The validation level may be acquired within a threshold time frame of a subset of non-invasive analyte measurements taken during the time period and/or at the end of the time period.

The method 708 may include determining whether a discontinuity exists between the level of the final non-invasive analyte measurement and the validation level (block 708 e). If a discontinuity exists between the validation level and the final non-invasive analyte measurement, the method 708 may include reinitializing the non-invasive analyte measurements to the validation level (block 708 f). If there is no discontinuity between the validation level and the final non-invasive analyte measurement, the method 708 may include validating the non-invasive analyte measurements as accurate (block 708 g). Reinitializing the non-invasive analyte measurements may include setting an initial non-invasive analyte measurement of a second time period to the validation level. After a number of time periods of reinitialization, the method 708 may include determining whether a pattern exists in the discontinuity data and obviating validation based on invasive analyte measurements (block 708 h). A size, direction, and/or time of the discontinuities may be stored sequentially in memory. If a pattern is determined, a prediction model of future discontinuities may be generated. Based on the prediction model, discontinuity may be anticipated and/or accounted for in non-invasive measurements. This may be done continuously. For example, a slope may be determined for predicted changes in actual analyte levels compared to non-invasively-measured analyte levels over a time period. The non-invasive analyte measurements may be adjusted to fit the slope. Validation measurements may be taken less frequently depending on a performance of the predictive model. Validation measurements may initially be taken daily, then weekly, then monthly, then annually based on a performance of the predictive model.

In various embodiments, a method of creating a predictive model may include: collecting a set of past data elements; predicting a future data element based on the set of past data elements; generating instructions for displaying the future data to a user; and/or transmitting the instructions to a user device, a non-invasive glucometer, or an invasive glucometer.

The set of non-invasively-measured glucose levels may include an individual non-invasively measured glucose level measured approximately concurrently with the second invasively-measured glucose level. The corresponding measurement value may be measured during the time interval. The future data element may include: a future glucose level of the subject; a trend of a future set of glucose levels of the subject; a difference between a future invasively-measured glucose level of the subject and a future non-invasively-measured glucose level of the subject; a difference between a future non-invasive glucose measurement reading and a future actual glucose level during a future activity of the subject; a correlation between the future activity and a future corresponding measurement value, the future glucose level, or the future set of glucose levels; and/or a correlation between the future corresponding measurement value of the subject and the future glucose level or the future set of glucose levels. The user may include the subject or another person.

In various embodiments, a method of creating a predictive model may include determining a past data characteristic based on two or more of the past data elements and predicting the future data element based on the past data characteristic.

In various embodiments, a method of creating a predictive model may include: validating the future glucose level or the future set of glucose levels by a validation measurement; training a predictive algorithm with a validation glucose level; in response to the validation glucose level being outside a threshold range of the future glucose level, increasing a future frequency of validating the future glucose level or the set of glucose levels; and/or in response to the validation glucose level being within the threshold range, decreasing the future frequency of validating the future glucose level or the set of glucose levels. The validation measurement may include an invasive glucose measurement. The validation measurement may yield a validation glucose level. The future glucose level or the future set of glucose levels may be measured non-invasively. The predictive algorithm may generate a predicted measurement of the future glucose level or the future set of glucose levels.

In various embodiments, the physiological characteristic of the subject may include: a hydration condition; a blood oxygenation; a heart rate; a blood pressure; a skin complexion; and/or an intensity of a wellness feeling. The wellness feeling may be indicated by: dizziness; nausea; sweating; and/or fatigue. The physiological characteristic may be measured by a non-invasive glucometer that also may measure the non-invasively measured glucose level of the subject. The non-invasive glucometer may include two or more sensors. The non-invasive glucometer may measure the physiological characteristic and the non-invasively measured glucose level using the two or more sensors. Readings by the two or more sensors may be compared to determine a physiological characteristic measurement and/or the non-invasively measured glucose level.

In various embodiments, a method of creating a predictive model may include identifying a trend in historical differences between historical non-invasive glucose measurements of the subject and historical invasive glucose measurements of the subject. Each of the historical differences may be between two approximately concurrent measurements during the time interval of the history of glucose levels The difference between the future invasively-measured glucose level and the future non-invasively-measured glucose level may be predicted based on an individual historical difference of the historical differences. The future invasively-measured glucose level and the future non-invasively measured glucose level may be predicted for approximately concurrent future times. The approximately concurrent future times may occur during a future time interval analogous to the time interval of the history of glucose levels.

In various embodiments, a method of creating a predictive model may include adjusting the future glucose level or the future set of glucose levels. The adjustment may be based on the correlation between the future corresponding measurement value and the future glucose level or the future set of glucose levels. The adjustment may be based on the correlation between the future activity and the future glucose level or the future set of glucose levels. A measured future glucose level may be skewed from the future glucose level due to the physiological characteristic. A measured future set of glucose levels may be skewed from the future set of glucose levels due to the physiological characteristic.

In various embodiments, a method of creating a predictive model may include: collecting a set of data elements; predicting a future data element of a second time interval based on the set of data elements; and/or generating instructions for displaying the future data element to a user. The set of data elements may include: a first set of analyte levels of a subject; a first time interval during which the first set of analyte levels is measured; a first indicator that is indicative of an activity of the subject during the first time interval; and/or a first measurement reading of a physiological characteristic of the subject. The first set of analyte levels may include a first invasively-measured analyte level and/or a first non-invasively measured analyte level. The physiological characteristic may be measured during the first time interval. The future data element may include: a difference between a second non-invasive analyte measurement reading and an actual analyte level during the second time interval; and/or a correlation. The correlation may be between two or more of: the second non-invasive analyte measurement reading; the actual analyte level; a second invasive analyte measurement reading measured during the second time interval; a second indicator that is indicative of an activity of the subject during the second time interval; and/or a second measurement reading of the physiological characteristic measured during the second time interval.

In various embodiments, a method of creating a predictive model may include scheduling a validation of the second non-invasive analyte measurement reading during the second time interval. A prompt may be scheduled to notify the user during the second time interval to validate the second non-invasive analyte measurement reading using the second invasive analyte measurement reading. The second non-invasive analyte measurement reading and the second invasive analyte measurement reading may be taken approximately concurrently. A method of creating a predictive model may include: scheduling a set of validations for a set of non-invasive analyte measurements taken during the second time interval; setting the frequency to increase when individual non-invasive analyte measurement exceeds a threshold difference from the individual invasive analyte measurement; and/or setting the frequency to decrease when the individual non-invasive analyte measurement taken during the second time interval is within the threshold difference. An individual non-invasive analyte measurement of the set of non-invasive analyte measurements taken during the second time interval may be validated against an individual invasive analyte measurement taken approximately concurrently with the individual non-invasive analyte measurement. The set of validations may include a frequency during the second time interval of validation measurements. The set of validations may include a set of randomized validation prompts for the user. The validation prompts are generated at randomly-selected future times during the second time interval.

In various embodiments, a method of creating a predictive model may include setting an alert to be communicated to the subject. The physiological characteristic may include a symptom of an imbalance of an analyte in the subject. A correlation between the second non-invasive analyte measurement reading and the activity during the second time interval may indicate the subject will experience the symptom. The alert may be set to be communicated to the subject when the correlation between the second non-invasive analyte measurement reading and the activity during the second time interval indicates the subject will experience the symptom. A predictive algorithm that predicts the data element may be isolated from a wearable device worn by the subject such that the predictive algorithm is inaccessible through the wearable device. The wearable device may be configured to non-invasively measure an analyte level of the subject.

In various embodiments, a system may include: an invasive analyte measurement device; a non-invasive analyte measurement device; and/or a processing device communicatively networked to the invasive analyte measurement device and the non-invasive analyte measurement device. The processing device may be configured to: collect a set of data elements from the invasive analyte measurement device and the non-invasive analyte measurement device; and/or predict an individual data element based on the set of data elements. The set of data elements may include a first set of analyte levels of a subject and/or a time interval during which the first set of analyte levels is measured. The first set of analyte levels may include a first invasively-measured analyte level and a first non-invasively measured analyte level. The individual data element may include a difference between two or more of: a second non-invasive analyte measurement reading; a second invasive analyte measurement reading; and an actual analyte level.

In various embodiments, the processing device may be configured to: continuously or iteratively monitor a current incoming non-invasive analyte measurement readings; and/or continuously or iteratively generate predicted values for the incoming non-invasive analyte measurement readings. The predicted values may be based on: the first set of analyte levels; the time interval; and/or times at which the current incoming non-invasive analyte measurement readings are measured. The times at which the current incoming non-invasive analyte measurement readings are measured may be analogous to times during the time interval at which the set of analyte levels were measured.

In various embodiments, the processing device may be configured to adjust a prediction of the second non-invasive analyte measurement reading based on a validation of a previous non-invasive analyte measurement reading with a previous invasive analyte measurement reading. The previous non-invasive analyte measurement reading and the previous invasive analyte measurement reading may be measured approximately concurrently. The previous non-invasive analyte measurement reading and the previous invasive analyte measurement reading may be taken previous to the second non-invasive analyte measurement reading.

In various embodiments, the analyte may include glucose. A hydration condition of the subject may skew the second non-invasive analyte measurement reading from the actual analyte level. Predicting the individual data element may include predicting the hydration condition and/or adjusting the second non-invasive analyte measurement reading to the actual analyte level. The set of data elements may include an activity of the subject performed during the time interval. The individual data element may include an influence of the activity of the subject on the actual analyte level. The processing device may be configured to prompt the subject to take an invasive analyte measurement reading. The set of data elements may include data indicative of an adverse symptom experienced by the subject during the time interval. The individual data element may include a trend in a set of the second non-invasive analyte measurement reading. Prompting the subject may be triggered by identifying the trend.

FIG. 8A illustrates a graph 800 showing a continuity between the first analyte measurement curve 704 a corresponding to the first time period 602 a and the second analyte measurement curve 704 b corresponding to the second time period 602 b, according to an embodiment. Some of the features in FIG. 8A are the same as or similar to some of the features in FIGS. 1A-7B as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-7B and not shown in FIG. 8A. The continuity may be confirmed by a validating analyte measurement 802 taken by an invasive analyte measurement device. The validating analyte measurement 802 may include a reinitialized analyte measurement. The validating analyte measurement 802 may match a final measurement taken by the non-invasive analyte measurement device during the first time period 602 a. The validating analyte measurement may confirm the final measurement taken by the non-invasive analyte measurement device is accurate. In an embodiment, the validating analyte measurement may match one or more measurements of a set of final measurements taken during the first time period 602 a. Match may refer to being exactly the same or falling within a threshold range of each other.

Continuity between the final measurement or a final data set of the non-invasive analyte measurement device and the validating analyte measurement 802 by the invasive analyte measurement device may indicate a trend. If the validating analyte measurement 802 matches the initial analyte level 504 a, the processor may determine the patient's analyte levels may be periodically consistent. The processor may further make such a determination if the first analyte measurement curve 704 a and the second analyte measurement curve 704 b have similar shapes. If there is a difference between the validating analyte measurement 802 and the initial analyte level 504 b, the processor may determine the patient's average analyte levels are changing. The processor may further make such a determination based on periodic differences between the first analyte measurement curve 704 a and the second analyte measurement curve 704 b, and or average differences between other analyte measurement curves corresponding to past time periods.

Continuous may be used to refer to obtaining analyte measurements. Continuous analyte measurement may refer to an uninterrupted progression of measurements. Continuous analyte measurements may refer to analyte measurements taken consecutively at significantly smaller time scales than a length of the consecutive time periods 602 a-e. For example, continuous analyte measurements during a time period of 24 hours may include analyte measurements taken 1 minute to 30 minutes apart, 1 minute to 15 minutes apart, 1 minute to 10 minutes apart, 1 minute to 5 minutes apart, 1 second to 1 minute apart, 1 second to 30 seconds apart, 1 second to 15 seconds apart, 1 second to 10 seconds apart, 1 second to 5 seconds apart, less than one second apart, and so forth. In another example, continuous analyte measurements during a time period of one week may include analyte measurements taken 1 hour to 4 hours apart, 1 minute to 1 hour apart, 1 minute to 30 minutes apart, and so forth. Whether analyte measurements may be considered continuous may depend on a time scale over which changes in the level of the analyte may occur. For example, when the level of the analyte may change dramatically over the course of a few minutes, continuous analyte measurement may refer to analyte measurements taken 1 second to 5 seconds apart, 1 second apart, less than 1 second apart, and so forth. When a minimum time period for dramatic change in the level of the analyte may include a few days, continuous analyte measurement may refer to analyte measurements taken 1 minute to 60 minutes apart, 1 minute to 30 minutes apart, 1 minute to 15 minutes apart, and so forth.

Continuous and discontinuous may refer to changes between analyte levels of consecutive analyte measurements. Continuous may refer to zero change between simultaneous analyte measurements taken by different analyte measurement devices. Continuous may refer to changes between consecutive measurements taken by the same measurement device that follow a curve such as the analyte measurement curves 704 a-e. Continuous may refer to changes between consecutive measurements taken by the same measurement device, where the consecutive measurements are within a threshold range of each other. Continuous may be contrasted with discontinuous. Discontinuous may refer to a non-zero change between simultaneous analyte measurements taken by different analyte measurement devices. Discontinuous may refer to atypical, unexpected, and/or uncharacteristic changes between consecutive measurements taken by the same measurement device. Discontinuous may refer to changes between consecutive measurements taken by the same measurement device that depart from a local slope and/or shape of a curve such as the analyte measurement curves 704 a-e.

FIG. 8B illustrates a method 804 of determining a change in a physiological feature based on a discontinuity between an initial analyte level and a validation level, according to an embodiment. Some of the features in FIG. 8B are the same as or similar to some of the features in FIGS. 1A-8A as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-8A and not shown in FIG. 8B. In various embodiments, the method 804 may be performed on one device such as the wearable device 100, the invasive analyte measurement device 302, the cloud-based server 306, the user device 308, and so forth. In various embodiments, elements of the method 804 may be performed on separate devices, where the devices from a health device network.

The method 804 may include receiving an initial analyte level from an invasive analyte measurement device (block 804 a). The method 804 may include setting an initial analyte measurement of a non-invasive analyte measurement device equal to the initial analyte level (block 804 b). The method 804 may include receiving time-indexed analyte measurements from the non-invasive analyte measurement device subsequent to the initial measurement (block 804 c). The method may include receiving a validation level from the invasive analyte measurement device (block 804 d). The validation level may be based on an invasive analyte measurement. The validation level may be acquired at an end of a time period such as the first time period 602 a. The validation level may be acquired concurrently with a final non-invasive analyte measurement or set of measurements taken at the end of the time period. In an embodiment, the validation level may be acquired whenever the user takes the invasive analyte measurement. In another embodiment, the user may be prompted to take the invasive analyte measurement to validate the measurements from the non-invasive analyte measurement device when the non-invasive analyte measurement device, the invasive analyte measurement device, the user device, and/or the server determines one or more of the non-invasive analyte measurements may be inaccurate and that measurement by the non-invasive analyte measurement device should be validated with the invasive analyte measurement.

The method 804 may include determining whether a continuity exists between the level of the final non-invasive analyte measurement or set of measurements and the validation level (block 804 e). If a continuity exists between the level of the final non-invasive analyte measurement or set of measurements and the validation level, the final non-invasive analyte measurement or set of measurements may be set as an initial non-invasive analyte measurement or set of measurements of a subsequent time period, such as the second time period 602 b. The method 804 may include determining whether the initial analyte level and the validation level are different (block 804 f). If the difference is non-zero and the final non-invasive analyte measurement and validation level are continuous, then the difference may include an indication of a change in the analyte level at times when no change might otherwise be expected. For example, the analyte may include blood glucose, and the invasive measurements may be taken during periods of fasting. A change in the invasive analyte measurements during periods of fasting may indicate a trending change in the analyte levels. Accordingly, the method 804 may include determining the trending change in the analyte levels based on the difference (block 804 g). The trending change may indicate an improving and/or worsening health of the patient. For example, the analyte may be blood glucose. The trending change may indicate a decrease in the patient's A_(1c) levels from diabetic levels towards non-diabetic levels.

In various embodiments, a method of validating a set of non-invasively measured glucose levels may include: receiving a first set of non-invasively measured glucose levels from a wearable device (e.g. the wearable device 100); receiving a validation level from an invasive glucometer (e.g. the invasive analyte measurement device 302); determining a measurement difference between the validation level and the final level; receiving a second set of non-invasively measured glucose levels from the wearable device; and validating the final level by a validation process. The wearable device may include a light source and a miniaturized spectrometer. The light source may be positioned in the wearable device to emit light through an artery of a subject (e.g. the muscular-walled tube 206 a or 206 b) as the subject wears the wearable device. The miniaturized spectrometer may be positioned in the wearable device to receive the light through the artery as the subject wears the wearable device. The wearable device may include a processing device that determines an amount of blood glucose of the subject based on the light received through the artery. The validation level may be measured approximately concurrently with a final level of the first set of non-invasively measured glucose levels. Validating the final level may be based on the measurement difference between the validation level and the final level or a measurement of another physiological characteristic. The validation process may include, in response to the measurement difference being greater than or equal to a first threshold difference, adjusting the second set of non-invasively measured glucose levels. The validation process may include, in response to the measurement difference being less than or equal to the first threshold difference, disregarding the measurement difference. In an embodiment, a change in the other physiological characteristic may correspond to a change in the amount of blood glucose of the subject. The validation process may include adjusting the second set of non-invasively measured glucose levels based on the measurement of the other physiological characteristic.

In various embodiments, a method of validation may include: measuring an initial hydration condition of the subject; measuring a final hydration condition of the subject; and identifying a drift in the first set of non-invasively measured glucose levels. The drift may be attributable to a difference between the initial hydration condition and the final hydration condition. In various embodiments, a method of validation may include: continuously or iteratively monitoring the other physiological characteristic for the change in the other physiological characteristic; and/or continuously or iteratively adjusting incoming non-invasively measured glucose levels when the change in the other physiological characteristic indicates the incoming non-invasively measured glucose levels are drifted from actual glucose levels of the subject.

In various embodiments, a method of validation may include generating a prompt designated for the subject. The prompt may request that the subject measure the validation level. The prompt may be generated after a fixed number of individual levels of the first set of non-invasively measured glucose levels is received. The prompt may be generated after a fixed period of time after initial non-invasively measured glucose level of the first set of non-invasively measured glucose levels is received. A second threshold difference may be calculated between two of the individual levels of the first set of non-invasively measured glucose levels.

In various embodiments, a method of validation may include: detecting a drift in the first set of non-invasively measured glucose levels; eliminating the other physiological characteristic as an influencing factor in the drift; prompting the subject to recalibrate the wearable device; prompting the subject to adjust a position of the wearable device on the subject to align the miniaturized spectrometer or the light source with the artery; prompting the subject to take a revalidation measurement comprising an invasively-measured glucose reading; receiving a confirmation from the subject that the subject has adjusted the wearable device; receiving the revalidation measurement; receiving a test non-invasive measurement reading; determining a revalidation difference between the revalidation measurement and the test non-invasive measurement reading; comparing the revalidation difference to a threshold revalidation difference; in response to determining the revalidation difference is within the threshold revalidation difference, confirming the test non-invasive measurement reading is accurate; and/or in response to determining the revalidation difference is outside the threshold difference, prompting the subject to perform another adjustment action or a calibration.

In various embodiments, a device for validating non-invasive analyte (e.g. glucose) measurements may include: networking hardware communicatively coupled to an invasive analyte measurement device, a non-invasive analyte measurement device, and a user device (e.g. the user device 308); and a processing device. For example, the device may include a cloud-based server (e.g. the cloud-based server 306). The processing device may be configured to (e.g. include instructions that, when executed, cause the processing device to perform various tasks): receive an initial invasively measured analyte level of a subject; receive an initial non-invasively measured analyte level of the subject; calculate a first difference; adjust the initial non-invasively measured analyte level based on the first difference; receive a first set of subsequent non-invasively measured analyte levels; and/or adjust individual levels of the first set of subsequent non-invasively measured analyte levels based on the first difference. The initial invasively measured analyte level and/or the initial non-invasively measured analyte level may be measured approximately concurrently. The first difference may be between the initial invasively measured analyte level and the initial non-invasively measured analyte level. The first set of subsequent non-invasively measured analyte levels may be measured by the non-invasive analyte measurement device after the initial non-invasively measured analyte level.

In various embodiments, a processor of a validation device may be configured to: receive a validation level from the invasive analyte measurement device; calculate a second difference; calculate a third difference; validate the final level to be equal to the validation level; receive a second set of subsequent non-invasively measured analyte levels from the non-invasive analyte measurement device; adjust the second set of subsequent non-invasively measured analyte levels based on the third difference; transmit the initial non-invasively measured analyte level, the first set of subsequent non-invasively measured analyte levels, and/or the second set of subsequent non-invasively measured analyte levels to the user device; and/or transmit the initial invasively measured analyte level and the validation level to the user device. The validation level may be measured approximately concurrently with a final level of the first set of subsequent non-invasively measured analyte levels. The final level may be previously adjusted based on the first difference. The second difference may be between the final level and the validation level. The third difference may be between the first difference and the second difference. The final level may be adjusted based on the third difference.

In various embodiments, the initial invasively measured analyte level and the validation level may be measured by the invasive analyte measurement device. The initial non-invasively measured analyte level, the first set of subsequent non-invasively measured analyte levels, and/or the second set of subsequent non-invasively measured analyte levels may be measured by a wearable non-invasive analyte measurement device. The initial invasively measured analyte level, the initial non-invasively measured analyte level, the first set of subsequent non-invasively measured analyte levels, the validation level, and/or the second set of subsequent non-invasively measured analyte levels may be routed through a hub. The hub may include the invasive analyte measurement device and/or the wearable non-invasive analyte measurement device.

In various embodiments, a processor of a validation device may be configured to: compile the initial non-invasively measured analyte level, the first set of subsequent non-invasively measured analyte levels, the second set of subsequent non-invasively measured analyte levels, the initial invasively measured analyte level, and/or the validation level into a time-indexed graph; and/or transmit the time-indexed graph to the user device. The time-indexed graph may include: a first indicator for the initial non-invasively measured analyte level; a second indicator for the initial invasively measured analyte level; a first curve for the first set of subsequent non-invasively measured analyte levels; a second curve for the second set of subsequent non-invasively measured analyte levels; a third indicator for the validation level; a fourth indicator for the final level; and/or a delineating line between the first curve and the second curve.

In various embodiments, the user device may be configured to compile measurement data into a graphical display.

FIG. 9A illustrates a graph 900 a of three analyte measurement curves 902 a-c corresponding to three non-consecutive time periods 904 a-c, according to an embodiment. Some of the features in FIG. 9A are the same as or similar to some of the features in FIGS. 1A-8B as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-8B and not shown in FIG. 9A. A first analyte measurement curve 902 a corresponds to a first time period 904 a. A second analyte measurement curve 902 b corresponds to a second time period 904 b. A third analyte measurement curve 902 c corresponds to a third time period 904 c. The second time period 904 b occurs after the first time period 904 a with one or more other time periods occurring between the first time period 904 a and the second time period 904 b. The third time period 904 c occurs after the second time period 904 b with one or more other time periods occurring between the second time period 904 b and the third time period 904 c. The first analyte measurement curve 902 a may have a first range of analyte levels 906 a and a first initial analyte level 908 a. The second analyte measurement curve 902 b may have a second range of analyte levels 906 b and a second initial analyte level 908 b. The third analyte measurement curve 902 c may have a third range of analyte levels 906 c and a third initial analyte level 908 c.

The second initial analyte level 908 b may be lower along the analyte level axis 504 than the first initial analyte level 908 a. Analyte measurements along the second analyte measurement curve 902 b may fall below analyte measurements along the first analyte measurement curve 902 a. A highest analyte level of the second range of analyte levels 906 b may be lower than a lowest analyte level of the first range of analyte levels 906 a. The second range of analyte levels 906 b may be narrower than the first range of analyte levels 906 a. The third initial analyte level 908 c may be lower along the analyte level axis 504 than the second initial analyte level 908 b. Analyte measurements along the third analyte measurement curve 902 c may fall below analyte measurements along the second analyte measurement curve 902 b. A highest analyte level of the third range of analyte levels 906 c may be lower than a lowest analyte level of the second range of analyte levels 906 b. The third range of analyte levels 906 c may be narrower than the second range of analyte levels 906 b.

The graph 900 a may reflect that the patient had lower analyte levels during the second time period 904 b than during the first time period 904 a. The graph 900 a may reflect that the patient had a narrower variation in analyte levels during the second time period 904 b than during the first time period 904 a. The graph 900 a may reflect that the patient had lower analyte levels during the third time period 904 c than during the second time period 904 b. The graph 900 a may reflect that the patient had a narrower variation in analyte levels during the third time period 904 c than during the second time period 904 b. The change in analyte levels and in the range of variation of the analyte levels from the first time period 904 a to the third time period 904 c may reflect changes in the patient's behavior affecting the analyte levels. In various embodiments, the analyte may include blood glucose. As the patient adopts healthy behaviors, the patient's blood glucose levels may decrease, and variations in the patient's blood glucose levels may decrease.

In an embodiment, the graph 900 a may be referenced to the coefficient of variation instead of the analyte levels. For example, the first range of analyte levels 906 a may instead be a first coefficient of variation and/or a multiple of the coefficient of variation, etc. The first analyte measurement curve 902 a may be plotted relative to the first coefficient of variation, etc. In another embodiment, the graph 900 a may be referenced to a standard deviation of the user's analyte measurements from a representative analyte measurement such as a mean or media measurement, a fasting measurement, an average fasting measurements, an average post-prandial measurement, and so forth. For example, the first range of analyte levels 902 a may instead be the standard deviation and/or a multiple of the standard deviation, etc. The first analyte measurement curve 902 a may be plotted relative to the standard deviation, etc.

FIG. 9B illustrates a graph 900 b of a continuous analyte measurement curve 902 d over three consecutive time periods 904 d-f, according to an embodiment. Some of the features in FIG. 9A are the same as or similar to some of the features in FIGS. 1A-8B as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-8B and not shown in FIG. 9A. the graph 900 b demonstrates a similar principle to the graph 900 a, except in a linear fashion. In an embodiment, the curve 902 d may be characterized by three consecutive time periods, a fourth time period 904 d (continuing the nomenclature of FIG. 9A), a fifth time period 904 e, and a sixth time period 904 f. The curve 902 d has a fourth range 906 d during the fourth time period 904 d, a fifth range 906 e during the fifth time period 904 e, and a sixth range 906 f during the sixth time period 904 f.

In an embodiment, a diabetic patient may have goals for improving the diabetic patient's health. The goals may include decreasing an amount of variation in the patient's glucose measurements, such as shrinking the patient's coefficient of variation and/or standard deviation for measurements during a given time period. Shrinking the coefficient of variation and/or standard deviation may include reducing a difference between a minimum measurement value and a maximum measurement value corresponding to the coefficient of variation and/or standard deviation. For example, the amount of variation in the patient's glucose measurements decreases from the fifth time period 904 e to the sixth time period 904 f. The fifth range 906 e and the sixth range 906 f may correspond directly to the patient's coefficient of variation during the fifth time period 904 e and the patient's coefficient of variation during the sixth time period 904 f. Accordingly, the patient's coefficient of variation may shrink from the fifth time period 904 e to the sixth time period 904 f.

The goals may include decreasing an average value for measurements during the time period. Decreasing the average value may include decreasing the maximum and minimum measurement values associated with the coefficient of variation and/or standard deviation. For example, the average value of the curve 902 d during the sixth time period is less than the average value of the curve 902 d during the fifth time period 904 e. Accordingly, the patient's coefficient of variation and/or standard deviation occupies a lower place on the graph 900 b relative to the analyte level axis 504 during the sixth time period 904 f than during the fifth time period 904 e.

The goals may include decreasing an average value for measurements during the time period and decreasing the amount of variation. Accomplishment of both goals is reflected in the difference in the analyte measurements and ranges, and therefore the coefficients of variation and/or standard deviations, between the fifth time period 904 e and the sixth time period 904 f. The goals may include decreasing the average value for the measurements without regard for decreasing the amount of variation, which may be represented by the difference between the analyte measurements, and therefore the coefficients of variation and/or standard deviations, between the fourth time period 904 d and the fifth time period 904 e. The goals may include decreasing the amount of variation without regard for the for decreasing the average value for the measurements, which may be represented by the difference between the analyte measurements, and therefore the coefficients of variation and/or standard deviations, between the fifth time period 904 e and the sixth time period 904 f. In various other embodiments, the goals may include increasing and/or decreasing, over time, the average value for the measurements and/or the amount of variation, and therefore the coefficients of variation and/or standard deviations.

FIG. 9C illustrates a method 910 of adjusting, over time, parameters associated with a patient's analyte levels, according to an embodiment. Some of the features in FIG. 9C are the same as or similar to some of the features in FIGS. 1A-9B as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-9B and not shown in FIG. 9C. In various embodiments, the method 910 may be performed on one device such as the wearable device 100, the invasive analyte measurement device 302, the cloud-based server 306, the user device 308, and so forth. In various embodiments, elements of the method 910 may be performed on separate devices, where the devices form a health device network.

The method 910 may include obtaining a representative analyte level and an analyte level range for a first time period (block 910 a). The representative analyte level may include, for example, the first initial analyte level 908 a, the analyte level range may include, for example, the first range of analyte levels 906 a, and the time period may include, for example, the first time period 904 a. The representative analyte level may include an average analyte level for the first time period, a median analyte level for the first time period, or a modal analyte level for the first time period. The representative analyte level may include an average of analyte levels less than a median analyte level for the first time period. The representative analyte level may include an analyte level for the user during a specified period of activity, such as during a period of fasting or during a post-prandial period. The representative analyte level may include a mid-range level relative to the coefficient of variation. The representative analyte level may include a level relative to the standard deviation of historical measurements of the user. The representative analyte level may include a representative rate of change of the user's analyte levels. The analyte level range may be a multiple of the standard deviation. The analyte level range may be a multiple of the coefficient of variation. The analyte level range may include a range of rates of change of the analyte level.

The method 910 may include obtaining a representative analyte level and an analyte level range for a second time period such as the second time period 904 b (block 910 b). The second time period may be consecutive with the first time period or non-consecutive with the first time period. For example, the first time period may span a day and the second time period may span a day, and a month may separate the first time period and the second time period.

The method 910 may include calculating a change in the representative analyte level and the analyte level range from the first time period to the second time period (block 910 c). The change may include an increase or a decrease in the representative analyte level. The change may be zero, which may demonstrate the representative analyte level did not change from the first time period to the second time period. The change may include an increase or a decrease in the analyte level range. The method 910 may include determining a quality of the change in the representative analyte level and/or the analyte level range (block 910 d). The quality may be good, bad, or neutral. For example, the patient's representative analyte level may increase, which may negatively impact the health of the patient. The change in the representative analyte level may accordingly be labeled as “bad” or “poor,” and so forth. The patient's analyte level range may decrease, which may positively impact the patient's health. The change in the analyte level range may accordingly be labeled as “good” or “positive,” and so forth.

In an embodiment, the change in the representative analyte level and/or the analyte level range may provide an indication of how well a health condition of the user is being managed. For example, a change in the representative analyte level that falls within a normal range for the user may be considered good, whereas a change that falls outside the normal range may be considered bad if it would move the normal range in a bad direction when calculated into the normal range. The normal range may include a multiple of the coefficient of variation, a multiple of the standard deviation, and so forth. The normal range may be a range of rates of change in the user's analyte level. The range of the rates of change may be a multiple of a standard deviation of the user's analyte level rates of change, a percentage of a full range of the change, and so forth.

The method 910 may include communicating the change and/or the quality of the change to a user such as the patient and/or the patient's healthcare provider (block 910 e). The communication may include audio, visual, and/or tactile communications. In one embodiment, a positive change may be indicated by a green arrow pointing a direction of the change, and a negative change may be indicated by a red arrow pointing in the opposite direction. In another embodiment, the communication may include a text alert delivered to a user device such as the wearable device 100, the invasive analyte measurement device 302, and/or the user device 308.

In various embodiments, the coefficient of variation indicators may include other multiples of the coefficient of variation such as three, four, five, six, and so forth. In one embodiment, the patient's coefficient of variation may be determined based on the patient's own historical analyte measurement variation. The patient's average analyte measurements may be significantly higher or lower than what may be healthy for the individual. Therefore, healthy measurements may be more than two of the patient's coefficient of variation from the patient's current measurements. Accordingly, as the patient's measurements become more healthy, i.e. lower, during a time period of a same coefficient of variation before the patient's coefficient of variation is adjusted, additional multiples of the coefficient of variation may be included on the coefficient of variation graph 1000 to account for the lower measurements. In another embodiment, the patient's average analyte measurements may be significantly lower than what may be healthy for the individual. Additional multiples of the coefficient of variation may be included on the coefficient of variation graph 1000 to account for higher measurements as the patient becomes healthier.

The normal level indicator 1002 a, in conjunction with the time axis 502 and the curve 506, may indicate when the patient's analyte levels as measured by the wearable device 100 are normal. Normal may refer to average levels of the analyte for the patient specifically. Normal may refer to average levels of the analyte specifically for the patient and during a time period. For example, the analyte may be glucose, and a normal glucose level may include the patient's fasting blood glucose level. Accordingly, the normal level indicator 1002 a may indicate to a user of the wearable device 100 when the patient's analyte levels are normal.

Coefficient of variation may refer to a range of values from a normal level of the analyte falling within a safe level. Safe may refer to an analyte level at which the patient does not experience adverse and/or dangerous symptoms due to the analyte level being too far above or too low below the patient's normal analyte level. A full coefficient of variation from the normal analyte level may indicate a level of the analyte at which the patient may begin to experience adverse symptoms. An analyte level two coefficients of variation from the normal analyte level may correspond to the patient experiencing dangerous symptoms. The coefficient of variation may be unique to the patient. Different patients may have different coefficients of variation. In an embodiment, the coefficient of variation may be related to a standard deviation of the analyte measurements from the normal analyte level.

Coefficient of variation may refer to a normal zone of analyte measurements. The normal zone may include a percentage of an entire range of the patient's historical analyte measurements. The normal zone may include a percentage of a range of the patient's historical analyte measurements dating back a specified amount of time. The amount of time may include a day, a few days, a week, a few weeks, a month, a few months, a year, and so forth. The percentage may include: fifty percent to sixty percent of the patient's historical range; sixty percent to seventy percent of the patient's historical range; seventy percent to eighty percent of the patient's historical range; and/or eighty percent to ninety percent of the patient's historical range. The normal zone may be patient-specific, i.e. each patient may have a uniquely determined normal zone based on the patient's own historical range. Using the patient's unique normal zone may enable individualized disease diagnosis and management.

The half coefficient of variation indicator 1002 b, in conjunction with the time axis 502 and the curve 506, may indicate when the patient's analyte levels as measured by the wearable device 100 are at, above, and/or within half a coefficient of variation of the patient's normal analyte level. The coefficient of variation may be calculated based on the patient's historical analyte levels, as opposed to historical analyte levels of another individual or a population. Similarly, the full coefficient of variation indicator 1002 c may indicate when the patient's analyte levels are at, above, and/or within a full coefficient of variation of the patient's normal analyte level. The two coefficient of variation indicator 1002 d may indicate when the patient's analyte levels are at, above, and/or within two coefficients of variation of the patient's normal analyte level. The real-time status indicator 1004 may be placed relative to the level indicators 1002 a-d to indicate a current, real-time status of the patient's analyte level, as measured by the wearable device 100, and relative to the patient's normal analyte level.

In an embodiment, the normal level indicator 1002 a may include a line parallel to the time axis 502 with the number “0” next to the line. The half coefficient of variation indicator 1002 b may include a line parallel to the time axis 502 with the number “0.5” next to the line. The full coefficient of variation indicator 1002 c may include a line parallel to the time axis 502 with the number “1” next to the line. The two coefficients of variation indicator 1002 d may include a line parallel to the time axis 502 with the number “2” next to the line. Positive values for the coefficient of variation indicators may be positioned below the normal level indicator 1002 a. This may indicate to a user, such as the patient, that lower analyte levels, such as glucose levels, are preferred. Similarly, negative values for the coefficient of variation indicators may be positioned above the normal level indicator 1002 a to demonstrate to the user that higher analyte levels are bad.

The lines and numbers associated with the level indicators 1002 a-d may have secondary visual indicators to provide additional visual indication to the user of the patient's analyte level. For example, the line and/or number associated with the normal level indicator 1002 a may have a first color, the line and/or number associated with the half coefficient of variation indicator 1002 b may have a second color, the line and/or number associated with the full coefficient of variation indicator 1002 c may have a third color, and/or the line and/or number associated with the two coefficients of variation indicator 1002 d may have a fourth color. The first, second, third, and/or fourth colors may fall on a continuous color spectrum. For example, the first color may be green, the second color may be yellow, the third color may be orange, and the fourth color may be red. In another example, the lines and numbers associated with the level indicators 1002 a-d may have the same color as each other, and a background of the coefficient of variation graph 1000 may display the spectrum of colors. A background behind the normal level indicator 1002 a may be green, a background behind the half coefficient of variation indicator 1002 b may be yellow, a background behind the full coefficient of variation indicator 1002 c may be orange, and/or a background behind the two coefficients of variation indicator 1002 d may be red.

The real-time status indicator 1004 may include a bubble. The bubble may be transparent to allow a background color of the coefficient of variation graph 1000 to show through the bubble, and/or the bubble may be filled with a color. The bubble may hover over the numbers associated with the level indicators 1002 a-d to indicate a proximity of the patient's current analyte level to the level indicators 1002 a-d. The bubble may be filled in with a color and may include an arrow pointing towards the curve 506. A portion of the color within the bubble may disappear as the bubble hovers over the numbers associated with the level indicators. The color within the bubble may change as the bubble moves relative to the level indicators 1002 a-d to provide a secondary indication of the patient's analyte level. The color within the bubble may change continuously along a spectrum ranging from green, through yellow and orange, and ranging to red. The color within the bubble may be green when the patient's analyte level is normal, yellow when the patient's analyte level is half a coefficient of variation from normal, orange when the patient's analyte level is a full coefficient of variation from normal, and red when the patient's analyte level is two coefficients of variation from normal.

The curve 506 may include a color fill between the curve 506 and the normal level indicator 1002 a, the half coefficient of variation indicator 1002 b, the full coefficient of variation indicator 1002 c, and/or the two coefficients of variation indicator 1002 d. The color fill may include a gradient ranging along a spectrum corresponding to the level indicators 1002 a-d. The color fill may include a solid color. The color fill may be semitransparent to allow a background color of the coefficient of variation graph 1000 to show through the color fill. The color fill may darken the background color.

The normal analyte level for the patient may be dynamically adjusted as analyte data is collected from the patient. For example, a processor associated with the wearable device 100, such as the processing device 102 and/or a processor of a networked device such as another measurement device such as the invasive analyte measurement device 302, a server such as the cloud-based server 306, and/or a user device such as the user device 308 may include programming and/or instructions to determine a normal analyte level for a most recent period of time. The period of time may correspond to a change rate and/or periodicity of the analyte. For example, the period of time may include a day, a week, two weeks, a month, two months, six months, a year, and so forth. Similarly, the processor associated with the wearable device 100 may include programming to determine a range of analyte measurements and corresponding coefficients of variation for the most recent period. The range and coefficients of variation may be dynamically adjusted as the normal analyte level is adjusted using similar methods as those used for dynamically updating the normal analyte level.

In various embodiments, the coefficient of variation graph 1000 may include an indication of a change in the normal analyte level, and so forth. For example, the coefficient of variation graph 1000 may include a first arrow placed on the coefficient of variation graph 1000 to indicate the normal analyte level is changing. The first arrow may point upwards on the coefficient of variation graph 1000 to indicate the normal analyte level is increasing and/or may point down on the coefficient of variation graph 1000 to indicate the normal analyte level is decreasing. The coefficient of variation graph 1000 may include a second arrow placed on the coefficient of variation graph 1000 to indicate the analyte range is changing. The second arrow may point upwards on the coefficient of variation graph 1000 to indicate the analyte level range is increasing and/or may point down on the coefficient of variation graph 1000 to indicate the analyte level range is decreasing.

FIG. 10B illustrates a current status display 1006 which may enable the wearable device 100 to succinctly communicate the patient's current analyte level, according to an embodiment. Some of the features in FIG. 10B are the same as or similar to some of the features in FIGS. 1A-10A as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-10A and not shown in FIG. 10B. The current status display 1006 may include the real-time status indicator 1004 and a set of current status qualifiers 1008. The current status display 1006 may communicate to the user the current status of the patient's analyte levels. The status may be relative to the patient's history, relative to population data, and/or relative to clinically-determined levels. The status may be relative to absolute levels and/or relative changes from an initial level. In an embodiment, the status may be relative to a coefficient of variation of the patient's analyte levels, a standard deviation of the patient's analyte levels, and so forth. The current status qualifiers 1008 may provide a qualitative, as opposed to quantitative, indication of the patient's current analyte level. In various embodiments, the analyte may include water. The current status qualifiers 1008 may provide a qualitative indication of the patient's hydration relative to clinical data on healthy hydration levels. In various embodiments, the analyte may include water. The current status qualifiers 1008 may provide a qualitative indication of the patient's blood glucose level relative to the patient's own blood glucose level history.

The real-time status indicator 1004 may move dynamically on the current status display to align with a current status qualifier 1008 corresponding to the patient's current analyte level. For example, when the patient's analyte level is high, the real-time status indicator 1004 may move to be positioned adjacent to a “Somewhat High” and/or “Very High” current status qualifier 1008. The real-time status indicator 1004 may change color to provide another visual indication of the quality of the patient's current analyte level. Similarly, the current status qualifiers 1008 and/or a background of the current status display 1006 may be color-coded to distinguish between different qualities of the patient's current analyte level and provide secondary visual indication of the quality of the patient's current analyte level. The current status qualifiers 1008 and/or the real-time status indicator 1004 may include words, letters, symbols, and/or colors that may communicate the quality of the patient's current analyte level to the user.

In an embodiment, the real-time status indicator 1004 may include a shape that may be recognized by the user as indicating the analyte measured by, and levels displayed by, the wearable device 100. The current status qualifiers 1008 include words arranged vertically on the current status display 1006 with lines between the words demarking a transition from one current status qualifier 1008 to another current status qualifier 1008.

FIG. 10C illustrates an embodiment of the current status display 1006 described regarding FIG. 10B including an absolute level indicator 1010, according to an embodiment. Some of the features in FIG. 10C are the same as or similar to some of the features in FIGS. 1A-10B as noted by same and/or similar reference characters, unless expressly described otherwise. Additionally, reference may be made to features shown in any of FIGS. 1A-10B and not shown in FIG. 10C. In an embodiment, the current status qualifier 1008 may include a color scale. The color scale may correspond to the patient's coefficient of variation. For example, the color scale may include green indicating the patient's analyte level is within a range of the coefficient of variation, yellow indicating the patient's analyte level is approaching a boundary of the range of the coefficient of variation, and red indicating the patient's analyte level is outside the range of the coefficient of variation. In another example, green may indicate a range of analyte measurements up to eighty percent of the patient's coefficient of variation, yellow may indicate a range of analyte measurements up to one hundred percent of the patient's coefficient of variation, and red may indicate a range of analyte measurements greater than one hundred percent of the patient's coefficient of variation.

In an embodiment, the real-time status indicator 1004 may include an arrow pointing to a region of the color scale corresponding to the patient's current analyte level. The current analyte level may be an absolute level, may be relative to a coefficient of variation of the patient's historical analyte levels, or may be relative to a standard deviation of the patient's historical analyte levels. The absolute level indicator 1010 may include a numerical indication of a value of the patient's current analyte level. For example, the analyte may include blood glucose. The absolute level indicator 1010 may include a numerical indication of the patient's current A_(1c) level and/or of the patient's current blood glucose level in milligrams of glucose per deciliter of blood (mg/dL). In one embodiment, the analyte level indicated by the absolute level indicator 1010 may be measured by a non-invasive analyte measurement device such as the wearable device 100. The absolute level indicator 1010 may update continuously as new measurements are taken by the non-invasive analyte measurement device. In one embodiment, the analyte level indicated by the absolute level indicator 1010 may be measured by an invasive analyte measurement device such as the invasive analyte measurement device 302. The absolute level indicator 1010 may update as new measurements by the invasive analyte measurement device are pushed to the wearable device 100.

The display may include: a mid-range indicator such as the coefficient of variation axis 1002; the half coefficient of variation indicator 1002 b; the full coefficient of variation indicator 1002 c; the two coefficients of variation indicator 1002 d; and a real-time glucose level indicator such as the real-time status indicator 1004. The real-time glucose level indicator may move on the display to reflect the new glucose measurements. The mid-range indicator, the half coefficient of variation indicator 1002 b, the full coefficient of variation indicator 1002 c, or the two coefficients of variation indicator 1002 d may remain static on the display as the coefficient of variation is updated such that a change in the coefficient of variation is indiscernible by the user as the user views the display.

In an embodiment, a method may include changing a spacing between two or more of the mid-range indicator, the half coefficient of variation indicator 1002 b, the full coefficient of variation indicator 1002 c, and the two coefficients of variation indicator 1002 d. The spacing may be adjusted from a first spacing to a second spacing. The spacing may be adjusted after a minimum time period. The spacing may be adjusted based on an accumulation of the change in the coefficient of variation over the minimum time period. The method may include overlaying the second spacing on the first spacing. The second spacing may be smaller than the first spacing or may be larger than the first spacing.

In an embodiment, a method may include: receiving a physiological measurement directly from a peripheral measurement device; and/or setting the coefficient of variation such that the new glucose measurements fall outside a range of the coefficient of variation. The physiological measurement may indicate a symptom of hyperglycemia or hypoglycemia. The physiological measurement may be taken approximately contemporaneously with the new glucose measurements.

In an embodiment, the change in the coefficient of variation may include a quantity and a direction. The change in the quantity may be indiscernible to the user.

The second line may indicate an upper range for an upper portion of the coefficient of variation above the mid-range level. The third line may indicate a lower range for a lower portion of the coefficient of variation below the mid-range level. A first spacing between the first line and the second line may be approximately equal to a second spacing between the first line and the third line. The upper coefficient of variation may be different than the lower coefficient of variation.

In an embodiment, the mid-range indicator may include a first color. The coefficient of variation indicator may include: a second color corresponding to a first multiple of the coefficient of variation such as a half multiple, a full multiple, two multiples, and so forth; and a third color corresponding to a second multiple of the coefficient of variation different than the first multiple.

The non-invasive analyte measurement may be acquired from the wrist-worn device via the invasive analyte measurement device.

In an embodiment, the coefficient of variation may be calculated on a server such as the cloud-based server 306. The server may be different from a measurement device that takes the invasive analyte measurement, such as the invasive analyte measurement device 302, or the non-invasive analyte measurement, such as the wearable device 100. The display may be generated on a user device, such as the user device 308. The user device may be different from the server and the measurement device. The server, the measurement device, and the user device may communicate over an Internet network, such as the health device networks 300 a-c.

The processing device may be configured to: receive measurement data and/or generate a coefficient of variation graph. The measurement data may include a coefficient of variation of the analyte levels of the subject and/or a current analyte level of the subject. The coefficient of variation graph may include: a time axis aligned horizontally on the coefficient of variation graph; an analyte axis aligned vertically on the coefficient of variation graph perpendicular to the time axis; a first horizontal line extending across the coefficient of variation graph indicating a middle of the coefficient of variation; a curve representing past analyte levels of the subject relative to the coefficient of variation and/or the current analyte level of the subject relative to the coefficient of variation; a second horizontal line extending across the coefficient of variation graph above the first horizontal line indicating an upper threshold of the coefficient of variation; and/or a third horizontal line extending across the coefficient of variation graph below the first horizontal line indicating a lower threshold of the coefficient of variation. The user interface may be configured to display the graph to the subject.

In various embodiments, units of the analyte axis may include: absolute quantities of an analyte indicated by the analyte levels; difference quantities of the analyte calculated from the middle of the coefficient of variation; and/or coefficient of variation intervals from the middle of the coefficient of variation. The middle of the coefficient of variation may be indicated on the analyte axis as a quantity of the analyte. The middle of the coefficient of variation may be indicated on the analyte axis as zero. The middle of the coefficient of variation may be indicated on the analyte axis as zero. In various embodiments, the indicator may include a bubble.
